great idea Greg !
I would suggest you post an enhancement-ticket for BP1.3

– Follow a Forum-thread = Subscribe to a specific Forum-thread. Would be cool to have……if it is simple to understand for users.
– Drop in “most followed Forum-Threads” , “most followed Blogs”, “most followed Users” , “most followed Group”, etc.
– This would replace what once has been “most active” , “most popular”.
– Skip the “Favourite” stuff.
