I was just informed, and have confirmed, that somehow my RSS feed stopped syndicating about 2 weeks ago. And then, on an entirely other date, the new Twitter feed stopped, but Facebook still works.
I think I have diagnosed the Twitter problem, which we will confirm with this post, that Twitter flagged and blocked the default URL shortening service my plugin uses for malware. It is either that or Coyoteblog has been blocked. Crossing my fingers I will see this on Twitter in about 5 seconds.
