...if you can't trust the employee to get their job done, why'd you hire them in the first place? If things have changed, get rid of them.

I get the dropbox thing, and I get blocking the usual suspects: "Weapons, porn, hate speech". But I never understood the netnanny against youtube (unless you have a small pipe), and the like. If you employees aren't doing their job because you've "allowed" access to certain things, get rid of them. Generally all you end up doing is creating roadblocks that keep other people from getting their job done. Perpetuates the "us against them" mentality in the organization.

Just my opinion. I don't know how many times I've come across a youtube video that I'd like to watch, related to the project I'm working on, but can't because we've blocked youtube because teachers can't watch their children.
