I'm discovering that a lot of companies/clients still aren't aware of social media. That's good news (more biz opps for consultants) and bad news (they are missing out on more biz opps for them).
I don't think we've reached the tipping point yet, but I can envisage this conversation:
"Hi there. I'm a consultant. Need some help getting started with social media?"
"Nah, got that covered thanks. What else can you offer?"
Apart from being the shortest new biz pitch in history, that also shows that even though we think this "gravy train" (for want of a better disrespectful phrase) is going to last for ever ... it's not. What other skills do you have? Can you write? That's always handy. Can you do research? That's useful too.
If you concentrate on only one discipline then you are going to get left behind. It will probably be sooner rather than later, actually.
