I can't say if it ever worked for me, as I've simultaneously moved to a new server and upgraded opengoo. But when I try one of the rss links, i get:
"Error
We are sorry, but OpenGoo is not currently able to execute your request. An Error Report has been sent to the administrator."
perhaps this from the log may help:
