I hear you on the subcategories, however, we've spent exhaustive amounts of time making the search function perform very well. In fact, you can search for "gambling" and then subscribe to your own personal RSS feed that will update each time there is a listing on FlipSquare that has "gambling" in it. You can be as specific or as vague as you'd like. This way you can monitor all sites for sale that would interest you and jump on the opportunities lickity split.
What do you mean you wouldn't buy a site that you don't have knowledge about...I didn't understand what you were saying there...
We're going to get some diggable posts on the blog soon but we'd really like to get some more feedback before getting
that many eyes on the site. A slow and steady launch is what we're going for here
Thanks for the feedback so far Matt!
