Scholar is trying to be more helpful to academic users. In the first post of a new blog they say they have recently added email alerts to Scholar. You can now create alerts for queries of your interest. When new articles that match your alert query are added to Google Scholar, they will send you an email update with links to these articles. This service has meant they have to update entries quicker than in the past with articles now being added twice a week.
Sounds as though this could be useful to some researchers.
Anybody tried it yet?
