I've been working out some legacy code from the Subtext days, trying to remove stuff that was cluttering up the code. I also made my feed standardized RSS 2.0 instead of the bastardized approach I had originally taken.
If you're using an RSS reader, the feed location is http://blog.robballen.com/feed.rss and no longer http://blog.robballen.com/Rss.aspx. Please update your bookmarks appropriately.
If you're having any issues, please let me know.
