Web 2.0 SF Magazines?

A discussion is beginning at SF Signal on this topic. The original idea, from Jay Garmon, is here. Interesting ideas being batted around. Clearly something has to happen to the magazines. Now I'm wondering if I could pitch stories on my own site, or this blog, and start collecting moolah? Hmmmm. If only. The subscription model wasn't unusual in the 19th century; I know Tom Sawyer was sold on that basis at first, at least in the US, and I think Dickens went that route as well (?).
