Twitter only allows you access to 100k users or so (tokens), and your business is at risk of being turned off. or App.net providers you access to 150k+ users growing user base. Plus an a free sign up, access to hosting for file storage, and permissive messaging.

IMHO that is only true if you want to be a Twitter clone or otherwise be in the same business as Twitter.
