OPML and Blogroll
Note to self: This seems to be a nice way to keep my list of RSS subscriptions in sync, which are currently redundantly stored in a local OPML file on my hard disk as well as at blogrolling.com.
It's a nice idea to use the XSLT service at W3C, and with XP's support for opening files from a URI it should be easy to import the server-side OPML into SharpReader.
