I’ve been posted to Twitter from Cullect since Cullect launched. Cullect.com/Garricks-Friends probably has as many blog feeds as Twitter feeds (yes its more about the people than their choice of publication).
This is a long way of saying I don’t see a difference between these two printing presses (I’ve said this before).
One of the projects on my Not Until 2009 List is to eliminate the space between things like Twitter and a weblog. Agnostic indeed. Feels like some things in WordPress 2.7 will make this even easier.
