After some discussion and sharing on Twitter, I pulled together this list of some of the upcoming conferences and events for those wanting to expand their horizons in marketing and social media (and a little Web 2.0 thrown in for good measure). This list is by no means exhaustive; if you know of a great event that marketing folks should know about, please include it in the comments with a link.
