I just wanted to announce my new Rails application, Launchly. Launchly is hosted on Heroku, which if anyone still hasn't used it, is awesome! Launchly is all about getting feedback and attention for newly launched web startups. We track everything about your launch so you can focus on what's important. It's also a great place to learn about the newest web launches and provide help shape the future of those apps by telling them what sucks and what rocks.
Check it out at http://www.launchly.com if it sounds interesting!
