Last week alone I spoke to 3 of my talented peers about this subject and was astonished at their stance. I was not astonished at their personal preference-- hey, use the tools or don't, I don't care as that choice is certainly not mine to make or impose upon another. It's up to each and every person. Oh how I love choice.
I'll only suggest my colleagues use these tools when I think they might find value in them... and if it were me, I'd be happy that my colleagues wanted me to participate since it signals that they value my opinions and like my company.
But what's astonishing (read: myopic) is when they take their personal preferences and apply those to their markets. And that's when I become mouthy.
Because we shouldn't be speaking for our markets, we should be listening to them speak to us--be it through their feedback, media preferences, product consumption and so on.
