1.	Posting to weblogs via Instant Messaging (IM) sounds appealing at first, but when you try it, as we did at UserLand, you realize it's great only if you never make a spelling or grammatic error, or spot a way to say something better in a few minutes.
2.	When it's time to make a change you have to use a command-line-interface for writing, which takes you back to the 1970s. It requires memorization of commands, and post numbers and stuff that users don't like to do.
3.	Now of course it's conceivable that AOL has solved this problem, if so I bet it leverages their ownership of two big IM systems. Do they use the popular blogging APIs to connect the two? Heh. There's the rub. This is what I have been warning about. AOL is a bigger company than even Google is (said with a hint of irony), and may not care to protect them, or the rest of the weblog tools vendors.
