So it looks like all you're grabbing is:
  1. date
  2. title
  3. description
  4. link
I have all of these in the RSS feed afaik. I'd be happy to add what's missing if you can pinpoint it. Other channels?
It's cool man; don't spend your time on it, thanks. Your feed does the minimum requirement, which is to provide a 'head-up' for site updates, which is just fine. I'm sure you've enough to keep you busy without having to service elements in the RSS feed. Keep up the good work and have a great weekend. Peace.
