The vague January prognostication by a guy who'll be rich from Twitter's IPO, profitable or not, was enough for the LA Times to say "Fred Wilson hints that Twitter is profitable." We know now that Twitter is already bleeding tens of millions of dollars this year ($69 million, to be exact). Even by shaky newspaper standards, that's a long way from profitable.
No response from Wilson about his wager, so far. I hope Chris O'Brien took the bet.
