I’m new to all this social media. I have been content with e-mail for a long time. Now I decided to take this to the next level, only to discover there are actually a lot of levels. I got this blog and a Twitter account up and running. Then I added Facebook. Now I’m adding Google +. Then what? Pinterest? Photobucket? Where does it end? I understand the need for competition to drive the market. But I don’t know where to draw the line. I just want it all in one place. But as usual it’s fractured. So maybe you can help me. What are the critical social media platforms? Which are not really necessary?
