My observations from these scans:
- An average of one or two blogs disappear completely during each cycle (i.e. their domain no longer works or the blog has been deleted).
- While it’s fortunate to only lose a couple every few months, it’s always sad to see them go and they leave a hole in the blogverse. Like losing friends.
- A large portion of redirect errors come from blogs changing their URLs (i.e. moving to new locations or changing the way they do links, etc.) and forgetting to also redirect their RSS feed. So don’t forget your RSS feed when you change things up, folks!
