Tweetmeme catching Twitter up

London-based Tweetmeme is rapidly catching up with Twitter‘s users if this chart is to be believed. It shot from less than 10,000 unique viewers per month to 14.6 millionin the US alone in August. Don’t believe everything you believe in the press though, Tweetmeme has not quite raised $650 million in funding – closer to two orders of magnitude less in fact.
