There's this weird polite / cultural thing going on in FFXI and FFXIV where shouting is viewed as rude.
I understand why shout spam is frowned upon, but for new players with no in-game friends to chat with, no LS, no vent, etc. the game can be very lonely and quiet. I've always been a fan of MMO's having general, ooc, trade, local, regional, and other misc. chat channels.
That way, you can shout spam the appropriate channel and get the info you need from the people that are lingering in that channel. If you don't want to see that spam, you simply turn that chat channel off.
In FFXIV, not only do people tend to ignore your shouts (and therefore not answer your important question), they think less of you for being rude and shouting.
