At the end of the day here at Socon 09 - it has been interesting as this social media marketing "unconfrence" has been in the top 10 Twitter mentions and right up there with TED! Go Us - here is a picture from Flickr, uploaded by one of the participants:

The day has been spent tweating, status updating and talking about everything but email Marketing, Search Engine Optimization or Web Design. So it has been interesting. Basically Social Media is about connecting with consumers during the buying cycle, but most importantly in the post purchase usage cycle. It can be for solve a customers product problem or more importantly allowing buyers to connect with each other and making it a manner that allows them to get more value out of your product or service.  I think that social media marketing will continue to be a good strategic topic this year, but 2009 will still be about trial and error.  As I typed that last comment, I think believe that is the point of social media marketing, try something, monitor it, get feed back and make changes. Good luck!
