Keith has 90+ answers and 21 endorsements in Startups Remember vertical search engines? They were all the rage. Oh, yeah, I still Google that. Will Quora displace vertical Q&A sites like Stack Overflow (stackoverflow.com)? Fred is partially right, but mostly wrong. It is easier to create a vibrant community Are there any Q & A sites that are better than Quora? around a narrow topic, but substantially less valuable: Vertical Q & A sites can be moderately successful but are unlikely to create billions of dollars of value or Is Beepl a better Q&A site than Quora? fundamentally transform the Internet. Is Google moving towards a face­off with Q&A sites like Quora, Stack Overflow over social search? Why? It is easier to build for the reasons Ben identifies: Dual­sided markets require hand­ crafting to ensure equilibrium between questions and expertise. Trying to balance these across multiple verticals simultaneously is very difficult. One can argue that this was a key mistake we made at LinkedIn Answers, although I am not persuaded it is the true cause. The problem to the vertical approach is that it produces subpar engagement and retention. It is extremely challenging to persuade users to revisit your site on a daily or even weekly basis if it does not serve a broad purpose. To wit, Craigslist is insulated from most e­commerce assaults because of its combination of personal ads, job listings and housing options. The personals and sex ads account for a majority of the page views and retention even though the other sections drive their revenues. Likewise, the general purpose Amazon is now on the precipice of eating up much of e­commerce: http://www.businessinsider.com/c... Back to Q&A: In a vertical site, you would never generate some of the most compelling Quora answers which are often very far removed from startups, venture capital and engineering, although mostly written by those who are professionally dedicated to those fields. (See the most popular answers for a sample of some very random topics: What answers on Quora have the most upvotes? ) Quora would feel like a professional obligation, not something to look forward to. Most people procrastinate chores.

Plus using this site has really made me impressed with how prolific most experts are across multiple verticals. The only issue I see with the horizontal approach is that a lot of people (myself probably included) overextend their expertise into topics they only have a birds­eye view of, and I see a lot of answers upvoted to the top that sound right but are ultimately less well informed than others. This is mostly limited to academic topics though. Written Jun 30, 2010 · View Upvotes Eghosa Omoigui, Stage/Geo­agnostic Tech Investor & Startup Advisor 402 Views Some really good points. Lawd i love Quora! ok, i'll freestyle some thoughts here... I think Fred was conflating two separate issues here: (a) why vertical approaches will always matter and, (b) what the historical horizontal approaches have yet to do successfully. Dual­sided markets by definition have a circular opportunity and problem. The opportunity is that one creates a base platform to pose queries and the problem is that one needs to source/attract/retain a x­section of domain experts who are best positioned to respond. worth noting that while the vertical approach solves the issue of presenting a constellation of specific interests that also attracts niche expertise, by definition, it will only attract a relatively small part of the broader 'net population. may be no less valuable though. i disagree with the premise that smaller/narrower equates to subpar engagement and/or retention. the key issue in my opinion is that the folks who run such sites seem less interested in the metrics that we as investors or valley­based/influenced entrepreneurs use to measure success and more interested in making sure they continue to offer a curated and high value environment. I have spent quite a bit of time researching q&a over the last few years so my insights come from a bunch of interviews, my thesis on how to attack the opportunity and general research. Random example: i like cars. a lot. and so i spend time on a variety of forums and message boards that are optimized (around brands/makes/models) for car lovers...those message boards may not have a ton of traffic (a measure by which we in the Valley may lead us to believe that they have thus failed) but as a source of advice, guidance, mentorship and recommendations, they are simply second to none because they have domain experts who truly enjoy offering advice and msg board members who appreciate the advice. and the visitors come back often. personally i am on there 2­3x/wk. i am still amused by the conversation thread (a few years ago) on one of the msg boards re: circumventing the nav­ sys safety lock­out on a Lexus ­ even some dealer service advisors were blown away by the elegance of the solution and were not afraid to acknowledge that they had had no idea it was possible. I would not go anywhere else to seek insights or if i do, i would take whatever i learn elsewhere and come back to seek validation. Period. Note that this is true even for what one may describe as 'subjective' answers. That said, dont fall for the CW that small is always positively correlated w/ lower case revenues. As a very very very senior exec w/ a well known 'fruit' company told me when i asked in a casual conversation why they priced their offerings so high at the expense of gaining oodles of market share, 'eghosa, we dont want everybody as a customer.' Needless to say, the company's revenues and GMs are UATTR so something is working well in their 'niche.' The horizontal approach by definition offers value to a much broader user base and its this user base that we all try to correlate to broader 'net value. The typical visitor gets to go wide but may not necc be inclined to go deep (or be so interested for that matter). I would posit that the q&q&a interactions in such sites are by definition light­filling and thus may fall below the nutritional IQ recommended daily allowance (and wont significantly change one's life). Yahoo Answers wins the blue ribbon here. https://www.quora.com/Why­does­Fred­Wilson­think­that­a­lot­of­vertical­Q­A­sites­like­Stack­Overflow­will­perform­better­than­horizontal­Q­A­sites­like­Q… 2/6 7/19/2016 Why does Fred Wilson think that a lot of vertical Q&A sites like Stack Overflow will perform better than horizontal Q&A sites like Quora? ­ Quora So where i see the real opportunity is a combination of Quora, StackOverflow, TextDigger and Aardvark. A broad horizontal platform w/ a constellation of topics that are auto­ organized and curated by vertical communities and most importantly, offers the ability to locate/cross­pollinate experts both inside and outside those communities/networks.

  • Corrective Or Critical? Commenting on Bad Questions in Q&A
    Corrective or Critical? Commenting on Bad Questions in Q&A Andrew W. Vargo1, Shigeo Matsubara1 1Kyoto University Abstract What kind of comments do Q&A community members prefer on bad questions? We studied this question on Stack Overflow, a large-scale community-run question-answer site with strong reputation and privilege systems and clear guidelines on commenting. Peer-production systems often employ feedback dialogue to engage with producers of low quality content. However, dialogue is only beneficial if it is constructive, as previous work has shown the adverse effects of negative feedback on quality and production. Previous studies indicate that feedback is likely critical, but the extent, orientation, and actors within this assumption are unknown. In this paper, we contribute a basic taxonomy of commenting and perform analysis on user types and community preferences. Results indicate that the most popular and frequent comments include criticism, and that different user types leave similar feedback. A better understanding of community feedback norms can inform the design of effective rules and incentives for peer-production systems.

Joel Spolsky and Je" Atwood had launched Stack Overflow less than two years ago, and it had already crossed the 175,000 mark in terms of registered users. The creation of an open platform where programming questions were promptly answered was an achievement in itself. However, Spolsky and Atwood faced their next challenge: coming up with a revenue model to monetize the popularity of Stack Overflow. Led by their frustration with other programming related Q&A websites, Spolsky and At- wood had started Stack Overflow to enable users to find answers to programming questions.

Users ask and answer questions from other users, and read existing questions and answers. The site was founded in June 2009, launched in private beta in December 2009, and made available to the public on June 21, 2010.[5] Quora aggregates questions and answers to topics and allows users to collaborate on them by editing questions and suggesting edits to other users' answers.[6] Quora's main competitors are social bookmarking sites like reddit, social networking sites like Yahoo Answers, LinkedIn, Answerbag and Answers.com, and expert question-answer communities like the Stack Exchange. History Quora was co-founded by two former Facebook employees, Adam D'Angelo and Charlie Cheever. D'Angelo quit his position at Facebook in January 2010 to create Quora[7] and said he was inspired to create Quora because he thought:[8] "that Q & A is one of those areas on the internet where there are a lot of sites, but no one had come along and built something that was really good yet." Quora's base of users grew quickly in December 2010.[9] In March, 2010 Quora received $11 million in funding from Benchmark Capital, valuing the start-up at $86 million.[10] Quora 2 Website Quora is designed to be an online social form of a knowledge market.
