We have confirmed reports that Google Reader's recommendation list feature stopped updating some time over the past day or so. The recommendation list is suppose to show you other blogs or feeds that you might be interested in, based on your current feed subscriptions at Google Reader.
In a Google Groups thread, one Google Reader user noticed that he/she stopped receiving recommendations. So he/she reported the issue, and Google confirmed the bug. Google said they hope to fix it in a day or so.
Roger from the Google Reader team said:
Thanks for reporting this. After a bit of investigating, we think we've found something that might be keeping some recommendations from updating. We're hoping to have this fixed by the end of the day. Please let us know if you're still having trouble after a few days.
