Let me just say, I think LinkedIn is underrated. On LinkedIn your brand voice can cut through the noise that exists on Twitter and Facebook. People following brands on LinkedIn are genuine fans of the brand or industry. Users following LinkedIn pages are extremely attentive and responsive. Additionally, LinkedIn Groups offer a unique opportunity to engage with users around a common, and often specific, topic. The appeal for a marketer is obvious, although many still haven’t jumped on the bandwagon yet. But it’s only a matter of time.
