Know-How Exchange : Social Media

It seems like most B2B marketers are a little behind consumer brands with regards to social, but a few B2B brands are really innovating in the space. I put together a few examples of what I believe to be great B2B social media marketing campaigns in this blog post:

Examples include GE putting employee tweets on their home page, Dow including social posts on campaign landing pages, and brands like Cisco, Oracle, National Instruments, and Jive using social media at B2B events.

I'm curious what other good examples of B2B social media marketing this community has seen or participated in.
