"engineers were people with great technical influence and if I wanted yahoo search to be successful, people around me had to see me use it."

Insane. If anything your time might be more valuable than someone else's, and if you can get your job done faster with google or bing, get the job done as efficiently as possible. Using Yahoo on campus, then using google off campus is even worse, because it gives the impression that it's solving your needs when it's clearly not.
