Blizzard hosted its first developer chat on Twitter in October 2009, and it looks like it was enough of a success to warrant another one. The second dev chat will be held on Friday, Jan. 15, at 5 p.m. PST with World of Warcraft's senior game producer and lead systems designer. The discussion will focus mainly on Patch 3.3: Fall of the Lich King.

To participate, you must submit your questions via Twitter using the #BlizzChat tag on Jan. 15 between 5-6 p.m. You can follow along on the official WoW Twitter page or wait for the full transcript to be posted on the official forums.
