Its a great idea, but I'm not sure its feasible. To subscribe, browsers have to go out of their way (interrupt their normal browsing experience) and join in.

Its a great idea, but I'm not sure its feasible. To subscribe, browsers have to go out of their way (interrupt their normal browsing experience) and join in. There's a better user experience by simple installing AdBlockPlus. And if you ARE willing to go out of your way, just use TipJoy or a similar service to donate to the site - PayPal would be better, actually, given the number of people who already have PayPal accounts. The parallel is with music, I'd think: You're looking to launch a subscription service when most people will just download the content for free or buy what they want to support off of iTunes. Only, your case is even worse: Napster/Rhapsody are doing moderately well with subscription models, and to get the rights to those subscription models, they have deals in place with the 4 major labels. The blogging (even the A-list blogging) community is much less consolidated - you'd have to strike an incredible amount of agreements to make your service universal. But you're thinking in the right direction.
