Here’s an interesting idea from David Singer, the guy who runs the VodkaFish blog. With AOL shutting down a number of the Weblogs, Inc. blogs (including AdJab, which Tom and I wrote for regularly) it would be fascinating to see the downward curve as people unsubscribe from the RSS feeds for those blogs. Not everyone, as he says, is going to automatically go and delete their subscription, it might take months before people get around to it. After all, there’s no additional cost to subscribing to a feed so it doesn’t really matter. I’d love to see this kind of report since I think it, as much as anything, would show how regularly maintain their feeds.
