social networking again

Ok, so as I blogged last time about all the social networking sites out there and how it was overwhelming.  I decided to to register on the sites that consistently popped up in the top 10: Facebook,  Twitter, LinkedIn, blogspot, Pinterest and Google+.. I am new to pinterest and Google+, so I am still trying to figure them out- which I will eventually... I'm not sure if these sites are right for our business yet, so we will see.
