There's more guilds in the game currently, than active players.

However, there are way more players (active or inactive).  The real trick is turning inactive players into semi-active or active players.  I honestly don't mind the number of Guilds there are... it allows players to bounce around until they find their group.  Personally, as a Guild Leader, I focus on the quality of person the player is rather than the activity and GP the player has.
