Notification to members for new group(s) created

When a new group is created, is there any notification mechanism to the members? I should not go to the Groups page and only then discover this amazing new group that I would be very interested in.
I feel something like the below will help:

1. A small section in the Devnet home page with group description (there is already sections for new wiki/posts etc)
2. Feed is sent to Global feed subscribers
3. Groups page has a "Whats new ..." section at the top
