OPML : Much cooler than Feeds
I really want to subscribe to people and concepts rather than just feeds. OPML is a great format for doing so-- the only problem is managing OPML subscriptions. I'm not aware of any aggregators that do this currently, but this is definitely possible through the NewsGator APIs.
Dave Winer started a new service for OPML sharing over @
http://share.opml.org. This is kind of cool since it lets me see what other users are reading as well as subscriptions that are like mine. One major flaw in the service though it that it is an OPML consuming service, and lacks the OPML publishing capabilities. What I'd really like to see is an infrastructure service like share.opml.org that lets you publish to and poll from such service from your favorite aggregator(s).
One such service I recently found is TagJag. There's a lot of noise feeds (most of the feeds are search feeds), but it's a great concept. There's definitely fun ways to use it in aggregators. To get an OPML feed for any given tag, just use the URL format
http://tagjag.com/discovery/[TAG]/opml (example:
http://tagjag.com/discovery/sharepoint/opml). What would be interesting is to see OPML from known users feeds in this format. For example, maybe I'd like to see Scoble's OPML but only for certain feeds? I don't want to read all of his subscriptions-- but perhaps I care about feeds he's reading tagged with "blogging", "rss" or "opml". This would be much more relevant to me than TagJag's
http://tagjag.com/discovery/blogging/opml opml feed.
We have a nice autodiscovery tag that's standard for RSS-- how about a standard OPML autodiscovery tag?
