I believe you can use and external blog and put that in your settings.
There are some bugs that still haven't got fixed for a long time so it is wishful thinking that you are going to get new features. I have proposed some that I think would be beneficial to the support and community theme, but more presently I'm leaning towards doing external application and/or facebook app, as I don't think any new apps would get implemented here. Although they are willing to contact me if they think they would be useful. Besides I'd want to use a proper framework such as RoR rather than the spaghetti junction PHP, that is part of the reason nothing gets done, it is a massive pain to trawl through, even if you are experienced, if you haven't tidied it up yourself.
