Social Networking from Work

My work has just unblocked access to social networking sites including Facebook, Myspace and Blogs (apparently)!

I guess that means they trust us enough to set our own limits as to when we access these sites on our personal time.

I feel like a teenager whose curfew has just been lifted :P

I'm still not allowed to access any web-mail services (Hotmail, Gmail, etc.) because it's apparently a network security risk.

Do the places where other people work block out these sites?

EDIT:

It turns out the unblocking of social networking sites is part of a larger new policy on the usage of Web 2.0 technologies.

It's refreshing that the organization realizes that it's pointless to pretend that employees aren't posting on blogs and joining Facebook groups and that it's better to allow access to these sites and educate employees on their responsibilities when posting on blogs rather than take the head-in-the-sand approach.

It's a surprisingly progressive approach for my company.
