Never listen to what people say in response to a survey:
Asking high-tech employees what will keep them in their jobs provides very different answers than the factors that actually drive retention.

On the 1st and 15th of every month I do a quick survey of what's new in a few journals. It was nice to see the contents on Radiochimica again.

If you build it, they will come. Lesson Learned
If you build it, they will come.
If you do not provide the service, they WILL go elsewhere.
If you make a good faith effort, your early adopters will assist you. Conclusions
Caltech is not typical.
YMMV – Your Mileage May Vary. In Fact, Your Mileage WILL Vary!
