As Ben tells me all the time, social networks are about, well, networking. That is, participation by people in a group of friends or colleagues about something they share. So, if you want to set about intentionally to make this part of your marketing campaign, hoping for that viral payoff down the road, how do you go about it? This post by Kimberly Krause Berg, one of the leading lights of the grassroots internet (a founder of Cre8asite), has a long list of good practices for participation in blogs, forums, social networks and all the online communities that form around some common interest. Sort of Miss Manners for the networld. And really good.
