The reason of the latest changes at weblogs.asp.net: Bandwith Usage
Ealier I blogged about some bloggers not happy about the changes at weblogs.asp.net, then Darrell post a comment with a link to Scoble's explation: Bandwith Usage issues, read the comments even Scott Watermasysk (.TEXT author) has commented, he promised it will be more configurable in the next version of .TEXT (it will be called Community Server :: Blogs).
I would like that RSS Agregators authors like Luke could work together with Scott and find a solution that make us all happy.
