How much value did your account generate for Twitter?

Twitter's IPO prospectus provided a handy basis for measuring the value that each Twitter user has contributed to the company's valuation. Now Time has produced a handy calculator that tells you how much Twitter "owes" you based on the value you created for it (importantly, this calculator does not tell you how much you owe Twitter for the value it created for you). It's crack-like fun. (via Sean Bonner)
