Google co-founder Sergey Brin said his company would be happy to talk with Facebook about potential ties but that the social network did not appear to be courting takeover bids.
Speaking in answer to a reporter's question at the 25th annual Allen & Co media deal-makers conference, Brin said: "If they come to us, we'd certainly be open to talking. But I think they're building a great company of their own."
Facebook membership has exploded in recent weeks to more than 29 million active members from 24 million in late May. By comparison, rival MySpace has attracted about 60 million unique users in the US and about 90 million globally.
