I don't like it, because it is not a standard like email (SMTP, POP, etc). If there were a Twitter RFC... Oh wait, there is! And it's been around since the 70's. Finger!

Why are they blocking sites in the first place? Is it about IT power and control? Is it an HR issue? Typically IT is concerned about blocking sites that are likely to be harmful. But the reality is, IT started being concerned with stuff other groups should be concerned with and Web blocking software became an IT-tool rather than a line of business tool. I could care less for example that an employee spends all day at Slashdot, ESPN, Facebook, etc... are they getting their work done? IT is not a substitute for HR or management. What is the IT-related reason for blocking a Web site? Bandwidth reasons; security reasons? The idea of blocking a bunch of sites, that really shouldn't be blocked is typically a result of default-policies, and not based upon sound judgement.

Prior to seeing this, I was just thinking about how Trent Reznor of Nine Inch Nails, just released his latest music (under Creative Commons), and is doing it in such a way in that he is exploring different avenues of making money. Then I was suddenly taken back to playing Quake years ago, of which I believe he did the soundtrack and in fact, there were NIN boxes laying about everywhere.
