We're looking for some feedback on a site that I've been working on. We have built up a small amount of data and are almost ready to go to beta. It's currently in alpha phase and we're looking for feedback. Feedback on bugs, interface, and overall value of the site is much appreciated. We can handle criticism, but the constructive kind is best. Check it out at TopCommenter.com. Thank you in advance.
