immedi.at – it's like RSS crack – or so they claim. Actually, it's probably going to be one of my favorite applications when all is said and done. Nothing to install, nothing to configure – just tell immedi.at what feed you want to keep track of, and when that feed is updated, it'll send you an IM via your favorite network. It doesn't import OPML yet, and account management is rudimentary – but this new service has promise. There used to be a buddy service that did the same thing, but it went away (likely due to bandwidth overages). Nifty URL, too. I grabbed an .AT domain the other day, but nothing's really come of it yet: glo.at (read: gloat).
