I need some clarification. I have been invited to join many social networking groups. I'm now on 5. Facebook, Ning, linkdin, Twitter, Myspace. I'm also in a couple Yahoo and Google groups. I've been invited to a few more, but I feel like I'm not really using the groups I'm already in to their best use. How is each group best used. I think Linkdin has a more corporate feel, Ning focuses on a specific group interest and Facebook is fun and personal, invitation only but open to many different groups of people in my life.
Eric started a second ning from his podcast, what is the advantage to that over just having a group here? Is there an advantage to have facebook and myspace? And what does Twitter give me that the other groups don't?
Any insights would be appreciated. RW
