Earlier this week, we (Ed Major and I) launched a new company called Orca Social as we see a need for large B2B companies to make better use of social technologies. Visit the website here.
The key for B2B companies is to learn to do social from within. The alternative is grim: If they engage external resources it becomes costly, slow and inauthentic. And, even more important, they miss out on the chance to break the silos and nurture a culture on which you can scale the social efforts to include e.g. social selling, social media customer service, social listening, internal collaboration etc.
