I stumbled upon your site via facebook (yes your ad buy seems to be working) from an audience perspective this site is a great idea (I shared it on facebook even). from a tech and web design perspective I think the site is definitely well executed and as someone who has had a few start ups, congrats on the launch and release, I know getting it done and launched is ALWAYS the hardest part. Keep on persevering, and good luck. I'll be reading your site and referring others often.
