That seems like the one to do, then.
For quite a while now I've been paying $3 a month for something called Achewood Premium Updates on a website called Assetbar (which lives at http://www.assetbar.com).
Basically, this is an extension to the existing and brilliant comic Achewood, with microblog style updates from the character's fictional lives, as well as subscriber-only strips and other assorted nonsense from the creator's brain.
My point is: wouldn't this be a fabulous way to monetize this site? After all, monetization is what Stephen talks about in his podcast about SF.C 2.0. It's a very small amount of money per month for what I'm sure would be a rich stream of content, and I know for a fact that I would sign up without hesitation.
There are already a few people doing this, including a number of webcomics like PvP (which I hate, personally, but there's something like 200,000 readers) and the brilliant Freezepop.
So, Mr. Fry, if you're reading this, and I congratulate you for reading all of it, or if some assistant has summarized it in a sentence: check out Assetbar. It really is a useful tool.
(Also, if you're wondering, no: I don't work there. I work at MasterChef Australia, which you should all watch if you live in the country.)
