I consider forums to be social media just like blogs and Twitter so to have them all work together is really the way things are going.
If you write a blog post in your wordpress blog there are plugins that allow for that post to be Tweeted to followers. It would be nice if new forum threads could be easily tweeted as well.
Also, avatars follow people around from site to site (using gravatar.com) - perhaps the same should apply for forums.
Forums will need to get on board with the rest of the social web.
