Readers: I suspect many of you are familiar with Google Scholar, Google's free approximation of what Thomson-Reuters offer for a fee. Scholar is a nice tool for searching references, though as a Google product it uses something similar to their pagerank algorithm, meaning that it can heavily bias searches in favor of papers that have been highly cited (though this can be tweaked or avoided in many ways).
Google Scholar gives you the opportunity to create a public profile as well, so that people can see at a glance your publications and their citations, keywords that you choose to describe your research area, instantly calculated metrics such as citation counts and the h-index, etc. (Some people like the Google Scholar h-index because it is systematically higher than the one from Thomson-Reuters, since it does a better job of catching bibliographic references in books and online resources. That, and our culture of encapsulating complex things in single numbers biases us toward preferring higher numbers.) I do have a profile, though I have mixed feelings about the score-keeping aspects of these things.
One reason I do have a profile is that Google Scholar has a feature that I've found interesting (if not necessarily useful) in the past: Based on your papers, where they're being cited, your research interests, etc., every few days Google Scholar comes up with suggested literature that it lists under a "My Updates" tab on your profile. These are new papers that either cite your work or Google's algorithm computes that you would likely be interested in the subject matter.
A month ago, I stopped receiving new "updates". The most recent one that shows up in my queue is from January 31. Moreover, when I look at my profile now, the "Co-authors" list, which previously had been populated automatically by Google Scholar based on my publications, is now completely empty. As far as I know, I have made no changes to my profile or settings. I have looked extensively and not found any reason why this should have changed. I used the feedback link to ask Google Scholar support about this, to no avail so far. I received an automated response with pieces of their FAQ list, and was told to reply to the email if that was not sufficient. I did so several days ago, with no response yet.
Has anyone else had these issues? Anyone have any suggestions for resolving this? I don't really care about the "Co-author" bit as I don't use that for anything, but I actually liked the article updates.
Update: The issue seems to have been fixed by Google! Woo-hoo!
