Social Media for SEO and Social Networking

It is clear that there is no escaping the importance of Social Networking. I don't think anyone would have realized how important this forum would be to e-commerce. I am still a newb when it comes to social media. I don't even know if newb is the word, I just hear my son use that word a lot for someon that is an amateur. I use Facebook and have viewed many ads and got hooked into advertising campaigns that would not have reached me otherwise. I think the important to using the networks is to know the different etiquette that is expected at each site. This will help prevent the "newbness". I also think it's important to try multiple networks to reach a diverse group of customers. You may be surprised about who may be interested in your product. I am still a newb but I am growing out of it.
