Awesome. Fellow Atlanta native I think this is really great, I hope you can start a trend here. I would love to be able to see all the start ups in my city.
This should link directly to <a href="http://atlantatechvillage.com/" rel="nofollow">http://atlantatechvillage.com/</a>.<p>Edit: Perhaps it should at least include the companies listed there for starters. =D
It would be nice to add a link to a crunchbase profile and add a startup I know in a more WIKI way... you need all startups in Atlanta to be aware of this page... there are quite a few, so you should make it as easy as possible to add a startup even if you don't work there. Let the WIKI gnomes do the work :)
Quick suggestion - for both semantics and SEO best practices, make the cities a subfolder instead of subdomain<p>Did you consider started.in/atlanta?
Just submitted -- fyi you have a bug in the form, if there's an error, it isn't displayed (Safari 7 anyway). I had to look at the XHR's in the console to see what error was being returned from the server :)
