Twitter To Add Money-Making Features
dreemteem writes "Twitter co-founder Biz Stone told reporters in Mexico City this week that the company expects to add revenue-generating features to the micro-blogging site in the fourth quarter, according to a report from Bloomberg.com."
The article didn't seem to mention it, but from what I have seen elsewhere, not all information that twitter has is available with the free api. It could be stuff like who is actually reading the tweets (rather that just followers), where they are, where the people tweeting about you are, standard analytic stuff that business really like to know.
I can see this being quite popular and making plenty of money for them.
