And now that everyone thinks I'm a complete dolt ;-), I realize should've been more clear and asked whether there's an intrinsic overhead in Keyspace itself that causes problems, or is it just the plain amount of CFs which is bad :-)

But I'm gathering that the Keyspace overhead is negliglible.

This might be a loaded question... what is a 'lot of CFs'? 50? 250? 500?  I say loaded because I know that its probably dependent on how many keys (size) are in a column family.

Yes, lots of CFs is bad means lots of CFs is also bad.
