But I would be afraid that somebody will figure out how to make a 13 character only twitter clone. This is a race that you can not win. Sooner or later some genius will make a service that allows you to broadcast nothing at all. Probably this service would even be free!1!.. killing all the other services in no time.
People want to be unique, but they're also lazy, so it's a compromise between the two. I think 14 characters strikes the balance.
Anyway, what's wrong with using numbers? Upper and lowercase? Unicode?
The hard thing about scaling a service like this is the social graph, AKA. when users have a lot of followers. So I'm going to use the freemium model and let users follow 10 or 20 people for free, and then start charging.
That way I'll start making money at the same time I have scaling problems.
Oh by the way, shouldn't you charge for being followed rather than following?
Will you give me a free premium account if I write an ebook about your app?
