I'm not sure if I'm keylogged or not (probably not, I don't see them wasting the server space/manpower) but our work filter closes out the strange and arbitrary things. Google image searches are left alone but it doesn't like the personal forum that WolFish and I leave messages for each other on, along the lines of "What do you need me to pick up at the grocery store?"
I keep half-expecting to get pulled aside by management about it and given the third degree. Broccoli is not technically a work purpose. Maybe they only really care about porn.
