I migrated the feed/rss/podcast list on the right side of the blog to use a neat new ajax widget (http://grazr.com) which is backed by an opml (aggregation of rss/links) file. Scroll down a bit and check it out!
I chose http://www.opmlmanager.com for my opml hosting. That allows me to store the raw opml on the web here: http://www.opmlmanager.com/opml/mpstx.opml. Then just point the Grazr widget generator at it, and wah la! An ajax opml/rss browser embedded in blogger blog.
