Search Others’ Bloglines Subscribed Feeds at Feedster

Michael Fagan IM’d me this afternoon with a neat but subtle addition to Feedster search. You can now search other Bloglines users OPML file (if its public). So, if you want to search the feeds that I read in Bloglines (which I don’t use anymore – the list is way outdated) for the keyword RSS, you would perform this search:

http://feedster.com/search.php?q=rss&inopml=ezraej

where ‘ezraej’ is my Bloglines ID. I don’t think that Bloglines offers this service (I know that I can search my own subscribed feeds, but not others). The trick is finding the ID for the person whose subscribed feeds you want to search. Useful? I think so.
