Here's news you don't hear everyday: according to the New York Times, via GigaOm, two venture capital groups were (are?) actually fighting over who gets to fund the next round for Twitter, a chatty microblogging service. The new investor (who hasn't been announced yet) will join Union Square Ventures, Twitter's current investor. Word is that the bidding war's winner will throw $15 million at Twitter—bringing its total VC funding to $20 million.

Addendum: part of what makes this story more interesting is the fact that Twitter has been struggling to keep its service up and running properly (although Valleywag has an interesting take on this, arguing that VCs love Twitters' breakdowns). Nonetheless, it's fascinating that VCs are fighting over funding the company, while Twitter's making admissions like the one they did on their official blog Tuesday night regarding another drop in service (via VentureBeat):

"We've gone through our various databases, caches, web servers, daemons, and despite some increased traffic activity across the board, all systems are running nominally. The truth is we're not sure what's happening."
