Blogger Andrew Sullivan has announced that he’s parting ways with the Daily Beast and launching a subscription-based blog, a move that ratings-challenged CNN host Piers Morgan has called a “deluded vanity flight into obscurity.” We’d love to think that Morgan was speaking tongue-in-cheek, but his recent “look at me!” Twitter rants have proved that he’s apparently totally self-unaware.

In a lengthy post at the Daily Beast, Sullivan thanked his readers for sticking with him “through the horrors of 9/11 and the Iraq War, past the Obama miracle and the odd lies of a former half-term governor whose name now escapes me.” So, just what is lurking behind that curtain that $19.99 a year will buy?

Hence the purest, simplest model for online journalism: you, us, and a meter. Period. No corporate ownership, no advertising demands, no pressure for pageviews … just a concept designed to make your reading experience as good as possible, and to lead us not into temptation.

Speaking of temptation, who’s reaching for the credit card?

Others are not so anxious to know what Sullivan is up to, now that he’s free from corporate obligations.

Still, the venture must be taking off. Sullivan reports that he’s taken in more than $100,000 already. What’s he going to do with all that money (after paying his staff, and paying for expenses and paying taxes)?

We’ll hang on to our 20 bucks for now, but the whole venture does raise an interesting question: who are we rooting for in the Piers Morgan/Andrew Sullivan cat fight?

A duel, huh? Do you have any idea how quickly Piers Morgan can reload a musket?
