Some people noticed some blog feeds that were showing posts from other blogs. Thanks in part to their quickly blogging the issue, we located and resolved the problem. A few people concluded that their blog’s feed had been compromised. We just wanted to let you know that there was no hacking involved.
The problem was caused by a bug in a new piece of software we are building to keep your blogs and feeds working quickly under heavy loads. If you saw wrong content in your feed, nobody hacked your blog or your feed. It was a software glitch. We are sorry about that. Blog on.
