Hi, NewsGator users (all two of you)!
The feed for this site seems to have been broken in NewsGator as they do some canonicalisation of URLs that doesn’t play well with the code for this site.
I’ve added a quick fix to the code to allow it to work again.
I’m not sure if the problem is on NewsGator’s end or mine, but I’ll investigate the relevant RFCs to see if I’m not canonicalising URLs properly on my end.
