Mark Earls is heading up a cracking free session at NESTA on Feb 9 in London.
If you want a clue about how this influence stuff really works, I'd rate this one as unmissable.

Book your place.
Mark is The Man when it comes to communicating Herd behaviour (hence his book Herd, right, and twitter moniker @herdmeister).
You'll also find him among the consulting network at BrandoSocial, I've been building :-)
