I've never been much of a forum, or online network user. The reason is, I like to interact directly with my customers and clients, and this doesn't actually happen in any forum.
Fortunately, the JL forum seems not to be so much full of people ready to slam other people. This is good!... because many other so-called top forums, are full of self-declared experts who put down what anyone else says, and fill the forums full of urban legends (disguised as reality).
So I tend to focus my time on webinars, and client coaching, and not on online networks so much.
This being said, I still use social networks to interact, though not as well as others. Business networks like Linkedin, for example, tend to be more responsive to new ideas about business, versus just having fun.
So if I were to go all out on business networks, the focus would be to provide useful information, interact in a easy, but professional tone, and not simply just be there to have fun.
Have a great 2012
