The other problem was that the skills weren't broad enough.
I'd really like to see skill trees. You take your first five ranks (or thereabouts) in general academic knowledge, and then from there on out you have to specialize, taking specific ranks for History, Arcana, Geography, etc. You take your first give ranks in acrobatics, and then specialize in Tumble or Balance. You take your first five in influence, and then specialize in Bluff or Diplo or Intimidate. It would allow for a lot more detail and robustness without clogging the character sheet, and it would make the game easy for beginners at 1st level while retaining the detail for more advanced players as they move up the ladder. It would allow a concrete list of general skills, while making it easy for DM's to make up subspecialties of them as needed. That's modularity in practice.
