I've had a custom feed from Lifehacker for over a year that's worked with no problem. It uses their tag format to narrow which posts I get. The URL for my feedreader looks like this:
http://lifehacker.com/software/not:AOL/not:vista/not:Apple/not:Audio/not:GTD/not:Mac/not:Mac%20OS%20X/not:Family/not:Kids/not:Parenting/not:Cars/index.xml
The past few days, it hasn't sent anything through, even though I know there are posts out there that fit my criteria. Does anyone know why it no longer works? Have they changed something in response to the gawker sites being hacked?
