Seems strange to appear now as its last month news..they been trying to get it noticed on Digg for about what 25 days?
But from I understand about the way the TOS read they do not have a case to stand on..
I had a chance to sign as writer but after reading the TOS realized that they could change program at any time without any guarantees to writers and thus declined.
But, however that is true with any writing content contract About.com, etc..
