I can't figure out what your site does (beyond "sharing tweets") by looking at it. I assume that information is hidden behind the login? I'm not going to sign in to a site just to figure out what it does, much less authenticate via another service.

Is this so I can tweet a bunch in a short period, and the service will spread them out over the day? I seriously have no idea.

Sorry if this comes across as rude, I don't intend it to be. I just cannot figure out what the service actually does.
