The RSS backlog was more interesting. It would have been easy to declare RSS bankruptcy and delete the backlog, but because the information I get via RSS is much more valuable than what comes through the email channel, I didn't want to do that. If I had done, I would have missed some of the interesting things which happened while I was away, such as the changes to Google Reader, being able to send items directly from Google Reader to CiteULike, and Friendfeed turning into Facebook (possibly).
So I slogged through the subscriptions, deleting half a dozen which had failed to add any value while I was away, by which time it occurred to me that I could probably delete half of the feeds I subscribe to without damaging the quality or diversity of the information I get via RSS. Like advertising, 50% of RSS is ineffective. The snag is, it's impossible to tell which half until after the event.
