Was there a search engine before Google? I'm no spring chicken (I can remember when computers had black screens with orange text and started at "C:" instead of a desktop) but I don't remember anything compelling before Google. I think I knew that Altavista existed but don't actually remember using it.
I have used info.com for years now. I collects the search results from Google, Yahoo. Bing, Ask and About and presents them in a compiled page. It just doesn't make sense to use just one search engine when a metasearch engine like info.com can collect results from multiple search engines for you.
I'm using Bing more, now that Google is screwing up their results page with unusable mini-instant previews that inadvertently pop-up when I never want them too.
Bing's ok, not the best, but it's cleaner than google.
fyi, I used to use altavista and askjeeves
