i think this must be harder than we can imagine, i remember gravity since i was one of the testers on that app, and look what it has become.

But at the very beginning looks a lot like witter... so is just a matter of time, i know we are a year after, but anyway we are not doing them so we cant judge...

i think maybe they should do a non-free app, i'll pay for it, if it works great and is what i need...
