If you aren't, you should be! And the best site is Yuwie. The layouts are easy to change and customize, the blogs are easy, and the best thing is that people will RUN TO YOU to be your friend! It's not like the other networks where people won't add you unless they know you (Or unless they are a freak) because people are expecting to help each other make money. Here is a link to my profile:http://profile.yuwie.com/drescher And here is a link to the marketing video:http://r.yuwie.com/drescher See you there! I will be your first friend.
Social "marketing" does seem to be all the rage. I am actually using many of the most popular sites (YouTube, Facebook, MySpace, Twitter, etc.) I had not heard about this one. I had not heard about this site - Is it new? I will check it out, thanks.
I don't have time and I'm not sure it's worth it. Depending you the niche I use Social Bookmarking Sites for some instant traffic and backlinks.
