this was posted by a corpmate in my EVE Guild...and I think it was a great article on what EVE is...at least from a meta perspective

After you read this, do the tuturial, and read all the help guides posted in the forums that relate to being a miner, missioner, pirate, etc...and spent a month or so in-game, you'll start to reach the point where you get the depth and breadth of what you can do...
conversely, if you play the game in a very 2 dimensional (WoW-like) fashion this game can bore you quickly. The missions are not as interesting as EQ2 or WoW (personal opinion) so if that's all you do it just doesn't work (again my opinion).
