Not a bad article. I hadn't heard of a few of these.

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.

Setting yourself up as a goog killer seems like a way to get ms interested in acquiring you though.

no twitter nor facebook will replace my google position in search, I use Google simply because it's fast and crawl a lot.

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.

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).

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.

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.

right now nothing will beat Google (only my secret startup :LL)
