This is from a survey out of the UK, but I suspect that the numbers are similar here in the US. The audience is Marcom people, being asked about workplace usage of social media sites (Facebook, Twitter, etc):

Around half said their IT departments blocked access such sites, however -- stopping them from monitoring what's happening with their brands.

That indicates a serious disconnect between the marketing and IT groups in question, and it needs to be fixed where it happens. I have a bunch of search feeds monitoring Twitter for various search terms, so that I can jump on top of things that mention the topics I care about. If you can't do that, you can't operate fully in today's media environment...
