And I like it a lot -- he starts with a preamble with some general networking tips, including finding social channels to join (many guilds and realms have a few social channels constantly filled with folks LFG or interested in playing socially) and putting together a solid friends list, then goes on to explain how to communicate (probably a great read for anyone in any part of the game) and then how to actually build a WoW group, from core classes to splitting up class roles. Very impressive -- while most veteran players have probably heard or done this stuff before, it's nice to see a clear, concise guide that starts at the beginning.
And it's even nicer to see a guide that emphasizes the social aspect of gameplay. Even here at WoW.com, we're all about gameplay tips, from profession insights to class balance discussion, but sometimes we overlook that to play a social game like World of Warcraft, you sometimes need to focus on social skills. As much as theorycrafting and gear upgrading can help, sometimes it's better to learn how to be friendly and social instead.
