Thanks for the positive feedback :)

I do have reservations about going after international and hyper-local markets at the same time.

International + hyper-local is more of an end goal than the begin stage. See http://news.ycombinator.com/item?id=4013608

And I have a concern that it sounds like you do not have a graphic designer to create the t-shirt designs

I know some contractors that are likely willing to help me out. Currently, I do not have anyone to structurally think/discuss/build this. I have reserved the summer to work on this and attend a bunch of networking events, hopefully someone will turn up!

Btw, if you think of anything else you'd like to discuss; don't hesitate to contact me at garm@frapp.it
