If you're wondering why my RSS feed was acting funny today; my blog was updated to CKS:EBE 2.0 Beta 2. There were no issues installing this release but I still needed to update my theme files (master page, XSL) because of all the new stuff in Beta 2.
I immediately fixed some minor bugs where relative URLs weren't correctly translated into absolute URLs (eg http://www.moss2007.be/blogs/vandest/blogs/vandest/Post.aspx?ID=2). These fixes can be downloaded here but the original solution file (*.wsp) has not been updated.
Also the 'Recent posts' needed to list the latest posts so I modified the xsl and sorted them descending. I guess that's up to you to do this or not.
