I am in Dallas, so this is interesting. Is the signup just for the Beta? If not, first thing, cut the cutesy landing page and let me find things. Craigslist might be dated and spam bloated, but I can find/price things quickly.
The sign up page is indeed just for Beta. You should sign up and give us your feedback when we start testing. :)
Are you connected to the Dallas startup community at all? We have won some local events in the past
Not really. Go to a couple of the meetups like Startup Happy Hour occasionally. I am a developer ("Chief Architect") for a local experiential marketing company and do mostly system design and iOS, Python development.
