We don't really mess with the blog tracker, so it is not a deliberate removal.

I have just tried a manual pull of the feed and apparently the feeds formatting is tripping up the forums feed reader, looking at the feed by eye I can see how it might (although nothing wrong with it I hasten to add).

I will try and upgrade the forums at some point and hopefully that will solve it. Finding the time to do an upgrade at the moment is a little difficult as it is best to do it in the early hours of the morning, which doesn't play well with a full time job so I am not sure when that will happen.
