If you want to play Online Game, wait for GW2 next month, or The Secret World now.

D3 is a SOLO game, the online connection are required for DRM (piracy prevention) and RMAH (real money action house)

90% in game time, you wanted to play alone.

Chat box?
Diablo 3 has the world WORST chat box system in game.

Party Play?
No exp gain increase, flatted MF/GF, mobs hp double up.
