I just participated in a Gather workshop exploring the new group formats and how they can benefit us all.
There are some amazing changes coming up - we'll have nearly autonomous control over our group design and functionality. I'm really looking forward to it.
If you've ever searched through your group members (in vain) or tried to feature articles - this new change is definitely going to make you happy. From the color, to the background, to the different elements (called modules) and their placement on the page - everything (including RSS feeds) will be possible. It's almost as if each group will be a mini-gather on its own.
I don't know why that's a "good" thing, but it is the direction this upgrade will take us. So start a new group, add your exterior links, pull in your blog, create your own "happy place" and invite everyone over to visit!
