Well I don't know about anyone else but it would seem to me that getting Twitter onboard would almost make Google invinsible..Or would it? http://mashable.com/2009/10/08/google-twitter/
Everybody wanna cash in the popularity. I think Google would survive quite well even without Twitter; but I am sure they would love the ready dollars.
twitter is famous right now, google really survive with out but its like a chain reaction, we can't stop twitter.
quite agree with you.. but i think google will not ignore twitter but it will try to get benefit from twitter real search.
