I've been wanting to put together some good OPML (Outline Processor Markup Language) files all week, inspired by Anne Zelenka's giant Blogher file and the interview with legal blogger Dennis Kennedy about the incredible potential for this medium.

An OPML file is, in this case, a single file you can use to subscribe to a number of RSS (definition) feeds all at once. This means that with one link you are subscribed to all future content from selected sources. I think that selecting a handful of key feeds in certain topic areas and offering those to other people is going to be a powerful way that information-overload gatekeepers help the rest of the world find and easily subscribe to the best news sources available. In this sense everyone who puts together OPML files is like an editor of anthologies; only the authors that the editor selects provide ongoing, dynamic contributions.
