After a patch once uldahs markets crashed for a whole week. during this week both gridania and limsa became very popular. everyone was everywhere. if they closed down uldahs markets for two weeks people would start selling elsewhere. I dont think this will turn uldah to a ghost town but provide a quick easy fix to the massive group in uldah.
The reasoning behind the uldah craziness was levs and market. All the good levs you wanted to do every lev cycle were all in uldahs areas. Because of this everyone also sold in Uldah, shouted and partied. I think SE tried to fix this offering some better rewards for other areas but it didn't really pan out.
Close it for a week, see what happens :D wont cost any money to do it but will help spread the player base imo.
And please dear god please.. no world chat >< that's the biggest most annoying feature I see in mmo's please!! *begs*
