Two things I haven't seen mentioned which might impact whether it is needed:

  1. Are the tablespaces Dictionary managed (not the default, but can happen with migrations or intended foolishness)? Might mean your SYSTEM TS has too much in the way of FET$ segments, if you've had lots of extents. Reorganizing the data TS could potentially only partially solve the problem. Or, it could solve it in a way that would be better solved by just converting to LMT.
  2. Some bad programming like creating and deleting lots of objects on the fly - won't get helped by reorganization, but might look like it will because SMON has been going nutso. See the last bit of http://groups.google.com/group/comp.databases.oracle.server/msg/adb5814c 9f6b8af0?dmode=source&hl=en for an example.
