Not a bad article. I hadn't heard of a few of these.<p>If anything is going to take market share away from Google, I think it's Twitter. Being able to search "live" information is really useful.
no twitter nor facebook will replace my google position in search, I use Google simply because it's fast and crawl a lot.<p>Google don't give best results (and no search engines can do) even human edited search engine can't do, just because information add up every day.<p>solution? May be a shared search, where people vote for the best results and comments, I see Google Wiki a good step, I alwas vote for the best results and comments on interesting links (or may be fav them).<p>If google succeed in this technology (considering the trend of the search queries), nothing can't beat him. Even if Microsoft does implement it, it won't succeed because it needs a lot of users to get votes and comments.<p>Twitter? No results are bad, they are good only for news, if twitter grow really (and not 60% quits!) then it may be a better place for news.<p>right now nothing will beat Google (only my secret startup :LL)
