Well now you can find out with Super Chirp and it’s basically adopted the iPhone App model by keeping 30% of the charge for its service and you receive 70% (is this going to become the norm why doesn’t someone try 75% / 25%…)

The service takes all your followers and allows them to sign up on its service you can then send these people direct messages and charges very between $0.99 to $9.99.  Something interesting that TechCrunch pointed out was that Britney Spears has over 1.7million followers and I’m sure there are quite a few followers that wouldn’t mind paying $1 – $10 for personalised tweets directly to them. Now imagine 100,000 sign up at $10 per month thats a nice little $700,000 extra per month, not too bad plus SuperChirp gets $300,000 (Maybe I should start up a competing site)
