Yeah...
Awful lot of anger going on here.
I use a bunch of Google's features, and the search almost exclusively. I've never had virus problems, and only ever had problems finding the information I'm looking for if it pretty much doesn't exist or shares common terms with other things.
I couldn't imagine -not- using Google, to be honest, and I'd hands-down recommend anyone who doesn't to do so.
But, there's no right or wrong answer.
You can't say "you don't use Google, so you're an idiot" or "you use Wikipedia, so you're an idiot".
If there were absolutely no merit to other search engines, then they wouldn't exist.
Similarly, with Wikipedia, and other sites that have followings or detractors - If you know how to use them properly, and do so, then they're good enough.
