Reddit is such a huge site that it really can't hurt to have a sub that monitors and lists current business who accept bitcoin. I don't really see the harm considering it's all organized under it's own separate subreddit that you can choose to subscribe to(or not).
I'm going to subscribe to the sub personally. Why not?
Here's how old I am: I remember Poodle Skirts, pet rocks, jelly shoes, beanie babies and Bitcoin. Since Bitcoin became the fad of the decade it seems like everyone that's got more than 5 minutes to spare is making a blog, website or wiki page showing how much they love Bitcoin. That's great and all but there is so much background noise on everything Bitcoin that I'm sure we can do without a few of them. We need another business directory like we need a hole in the head. I better list might be a list of places where you can walk in and buy Bitcoins immediately because you need some coin right now to spend at one of those businesses. That's going to be a much smaller list.
