Should Google be afraid of the likes of Facebook, and Twitter? Can social networks add anything groundbreakingly beneficial to search engines?
haha- you haven't used google wave then. I think they are embracing it rather then compete and coming with new ideas to build off of. also,things link twitter does provide information in real time and I feel the search engines agree adapted. this is all my .02c
Twitter is the most useless pointless thing that I have ever seen, Facebook is fairly good. But what can they do to Google?
No, if anything becomes large and useful enough to google they buy it. Google has no fears, apart from long power cuts, lol, as long as we can get online each day, they have nothing to fear.
I think Google must not fear this top social networks, because Google is the number 1 search engine and most of the internet users start surfing by using Google.
