I think it would be great if we have a community for low-budget startups to help each other. Getting new users is hard. And you don't get a real appreciation for how hard it is until after you launch. That I learned from my last project. So, I created the "Post Launch" community because I realized that there must be a lot of people in a similar situation like mine: launched and trying to market their startup. I hope we can use it to share marketing ideas, arrange banner exchanges, and so on. Is that along the lines what you're thinking?
About cool the startups sidebar, that would make a great community!
What do you think about that?
