Question : Blocking Blogging?

My client would like to block any type of "blogging" done during work hours.  While i realize how to block acess to sites that allow blogging is there any way to block the actual act of "blogging" while not blocking the actual websites that offer the avenue to blog?

Answer : Blocking Blogging?

Short answer is no. You can try blocking the major blogging web sites, but this is more a job for "usage policy" rather than some technical means.
