I think there are a couple of feeds, one with only the new entries and one with all the comments, which might be restricted to members only iirc…

While I generally consume internet content via RSS in Reeder app, I subscribe to just new first posts there. I prefer the Discourse interface of TBTalk, so I saved it as a Web App on my Mac and it’s open most to the time for frequent interaction and posting of my dumb ideas and supposed-to-be-funny comments… 
Oh and efforts to help and offer compliments and thanks of course.
