I do think that the amount of retro-themed discussion has dropped of significantly. I'd like to think I do my part. In fact, just yesterday I started a thread about a quasi-retro videogame!
Also, someone made an article that got voted #1 on that digg website, that's pretty good.
Also, Coolhand, you do come off sounding like a whiny little so-and-so, so why not make some awesome retro threads and get this place hoppin' again!
