Are Kooday, KuleSearch and TagVillage really able to beat Google?

We already knew about Kooday and a few weeks later came KuleSearch which I find to be a copycat of Kooday really. But now there's a new program on the block called TagVillage. It does show some similarities with Kooday and KuleSearch but TagVillage will be integrated on facebook and they will enhance social functions. With all these new programs on the web I am really curious on whether they will be able to beat Google or at least gain a decent market percentage. [b]What do you think? [/b] P.s. If you want to join TagVillage you can only join using someone's referral link. I have one in my profile but you're free to use someone else's. I also have a link to Kooday there.
