It would be nice to have temporary RSS subscriptions in Bloglines, or another RSS aggregator. You know, for those feeds that you know are only going to be around for a limited period of time, like an event feed, or comments on a post like this one on alexh’s blog.
I’m subscribed to the comments feed of that post, so I can make sure to see any new comments posted after mine, but after a short period of time, that feed isn’t going to have anything new in it. Wish I could tell Bloglines to “subscribe for n days” or something, so I don’t end up with a bunch of these stale feeds that I have to clean out after a while.
Anyone know of an aggregator that can do this? Any Bloglines folks reading want to put this on the wish list?
