It always amazes me when people are hostile to new ideas and new business practices. There's a big difference between trying to understand how you might implement social media in your business or organization (a good question), or whether it will have value for you (also a legitimate question) AND blanket stating that it's all a load of crap. 

It's especially troubling when you're dealing with communications pros fighting new strategies and tools for communicating.

On the plus side, it is a good way to screen out the early adopters and those who want to learn from the stick-in-the-muds, stuck-in-a-box crowd.
