Created in 1990 by Tim Berners- Lee, the web quickly became the most used hypertext system in the world, and most browsers default to indicating hyperlinks with an underline. To answer the question of why the underline was chosen over competing demarcation techniques, the thesis applies the methods of history of technology and sociology of technology. Before the invention of the web, the underline–also known as the vinculum–was used in many contexts in writing systems; collecting entities together to form a whole and ascribing additional meaning to the content. -

Usenet Gopher
Usenet Usenet is a worldwide distributed discussion system. It was developed from the general-purpose UUCP dial-up network architecture.

Usenet resembles a bulletin board system )++,* in many respects and is the precursor to Internet forums that are widely used today. Usenet can be superficially regarded as a hybrid between email and web forums. .iscussions are threaded$ as with web forums and ++,s$ though posts are stored on the server sequentially. Usenet is a collection of user-submitted notes or messages on various subjects that are posted to servers on a worldwide network. Each subject collection of posted notes is known as a newsgroup.

FIRST, members must not supply CFIC with their company email addresses. That is, companies that they work for. (If you own the company, that's different.) All email on a company's server can be read by any supervisor. All it takes is one pro vaccine activist to get hold of our mobilization alerts to throw a monkey wrench in all of our efforts. Thus, do not supply me with a company email address. We can help you get an alternative to that if necesary. SECONDLY, CFIC needs members' email addresses to supply important information to mobilize parents to do things that advances our goal to enact our legislative reforms of the exemptions from vaccination. That has always been CFIC's sole agenda. CFIC has been able to keep the membership fee to zero because we don't communicate via snail mail. But people change their addresses frequently and forget to update CFIC. When this happens over the years, that member is essentually blind and deaf to us, and is no longer of any value to the coalition---your fellow parents. Therefore, it warrants me to require that members supply CFIC with their most permanent email account. That means the email address of the company in which you are paying a monthly fee for internet access, be it broadband or dialup service. -
