I use iGoogle to collect a number of RSS feeds originated from blogs, in addition to a few of Google's MSM-originated feeds. The updating rate on the blog feeds has gotten slower and slower over the last few weeks. Right now, none of my non-MSM feeds have updated on the iGoogle pages since Thursday, two days ago. When I click through to the blogs, most of them have at least one post since then. I doubt all of their feeds happened to break at once.
What's going on, Google? I'll have to move my feeds elsewhere if you've gone unstable.
