All I'm going to say is, give it a shot and see where it goes. Like lebasiara said, don't you think DB thought about it. An owner of a business would only want to make his company to succeed.
Personally I am going to hold my judgment on this topic. If the site succeeds, then great because we all win. If it fails, then you can laugh and say I told ya so. But then again, you can't say DB didn't try to create change. Nowadays any joe schmo can start their own forum, so we need the differentiation.
