Fair enough! I suppose they are trying to compete with UrbanSpoon and other such "random place to eat" apps. I wonder how they see SMS working over an actual smartphone app?
On one hand, SMS allows all phones to be used for the service, but conversely disables the ability to use pretty graphics. Perhaps they will eventually offer both.
Edit: Sorry, corin_, thought you were the OP for a second. Reworded to more generic questions :)
Your service is awesome, but competition combined with limited availability is going to be a tough climb.
Do you have any revenue plans? I assume you're using TextMark, correct? How many users are you currently paying for (if you dont mind, or which price tier)?
Looks like a cool idea, I hope you find a way to monetize it!
