Dave Winer has created a catchily-named service – Share Your OPML. It doesn’t do anything very clever yet, but put together with some collaborative filtering software I am sure it could… To explain for the 99% of the world who have better things to do with their time than memorising TLAs (Three Letter Acronyms) or in this case FLAs – RSS readers can normally import and export OPML files which are simply lists of the sites you subscribe to. What ‘Share Your OPML’ does, then, is let you compare what blogs and other news sources you read regularly with others. Blogrolling, which has a much bigger installed base, could do this too but so far it hasn’t done much with its data (except produce its own top 100 list).
Anyhow, if those of you who do read this via RSS could pop along to that site and sign up – you might push this humble blog into Winer’s top 100!
P.S. If you’re wondering what on earth an RSS reader is, I “posted about that”:http://blog.org/archives/cat_weblogs.html#000880 here too.
