Oops -- I overlooked the "customer point of view" part.

So from the user's point of view, what do you want this site to be best at? (Express it as something the customer wants to do, which you enable them to do faster, cheaper, easier, better...)

Users generally search for a particular kind of group -- such as a "support group" (or a "interest group", etc.). The site should help to facilitate making such connections -- and also foster connections among the groups themselves (perhaps thereby avoiding duplication and/or increasing collaboration, etc.). Does this make sense to you?
