Social Media Profile and Diversity

[JesusD]

Hey everything, how is it going?

I am fully convinced of the importance of Social Media. I already witnessed the power of social with my facebook fan page. I am fully implementing facebook, twitter, youtube, and pinterest. I am starting to use Google +.

Is there any other social "must" for companies in order to include them on my social media profile? such as Linked In, Scribd, SlideShare. etc..

I forgot to mention we are specialized B2B Ecommerce company.

We use LinkedIn predominantly in the B2B space and find it is a great way to engage i industry discussions and also personal and company branding. For B2B social marketing my personal vote is LinkedIn #1!
