On our network we are focused on exchange of information and we use groups for different topics of interest, Science, Morality, Living, Politics... Groups are very active both on their comment walls and in their forum and most of them have their own set of pages. The majority of our members are customarily members of multiple groups. It's a bit like subscribing to different sections of a magazine. It's an invaluable feature for our network.
Yet there are virtually no tool at the network management level to handle or tweak all this activity.
I think there is a lot of room for improvement in that respect.
Hopefully Ning's new management's publisher culture will weigh in on how the Groups feature can be used to much better effect =)
Any other tools you'd like to see to help manage and promote your groups?
A good list, in addition having more than one RSS feed would be nice.
The groups are not as easily found by Google etc so indexed pages can be slightly out of date.
