Actually, Twitter's users are worthless. They are a cost to Twitter -- and they bring in no revenue (yet). (Obviously this doesn't apply to their new business/commercial accounts).

And Twitter's user base is about 6 million, which is also a far cry from Facebook's 50 to 175 million, depending on what number you believe.
