Google News has been known to be generous in adding publishers to Google News index. But recently they have come under fire for being too spammy and has dropped some publishers with their new algorithm.
Google News representative, Harvey P., said in a Google News Help thread that throughout the remainder of the 2010 year, Google News will slow the process of including and reviewing new publications into the Google News index.
Harvey said:
I assume this has to do with Googlers taking some time off for the holiday season and not the spam issues people have been complaining about.
I should note that in February 2009, Google added over 20,000 publishers to the Google News index and has been rapidly adding more since. The Google News team can use a little vacation.
