Unless I missed it somewhere (and if I did please point it out to me)...
I think a good idea is a bot that would allow you to insert CB profiles into your Joomla! content items. This would allow you to feature members - member of the month, most helpful member, etc.
There is already a plug-in that allows you to insert a link to a CB profile. Perhaps this could be taken one step further so that instead of a link it would allow you to insert the avatar (photo) from a profile. Then it would just be a matter of writing up some Joomla! content to go with the avatar.
For inserting Community Builder profile link to content. Use {cb_profile}username{/cb_profile} or {cb_profile=username}...whatever...{/cb_profile}
