@bix, it’s interesting to see others experimenting with these sorts of things. I hadn’t thought of adding any newsletters (and I don’t subscribe to more than one or two), but I’ve built a huge, categorized following page which includes OPML subscription links as well.
There are some details and links to how I did it in WordPress for those who are interested: From Following Posts and Blogrolls (Following Pages) with OPML to Microsub servers and Readers.
