Google Alerts?
system
This could be old news...
Everyone knows that you can sign up for Google to send you alerts about a news items that match a query. However, it looks like it also allows you to get alerts whenever something is added to the Google search results for the same query. So everytime something is added to your favorite obscure query, it will let you know
It's interesting that this isn't offered through the main Google portal... I wonder if this is a feature or a bug. That is, are they rolling it out slowly and it just happens to be activated (or at least you can get to it) through Google News?
