The latest feature drop is a parental controls infrastructure. You can find out more on (towards the bottom of) the help page. One of the key components is a tool to allow you to turn any of the site features on or off - either for you or for your children. This combined with subscriptions lets you fine tune exactly what you wish to see when you visit. I've been using this immediately to provide different feature sets to the music portal vs. the community portal vs. software engineering portals.

As always, this is just a hint at the types of things you can do. Any member for instance can turn off chat, the photo ratings, guitar chord charts, or anything else they don't care about.

I think I'm finally running out of website features to implement...
