1. When left to my own devices. Between 10am-2pm. After 7pm. Late night.
2. On the fence. Helpful when you need to work with others--if you each have predefined work hours every day it's easier to know when they're available. I don't like them though.
3. I don't, because I'm pretty fast and loose with organization so I'm not a good example. ;) I take care of whatever the interruption is and turn back to what I was doing. I wish others would do the same instead of whining about OH GOD WHAT NOWWWW.
4. I am neither hacker nor businessy guru type, I am usually in a support role. INFP
5. In an 8hr workday I would be in IRC the whole time, answering more questions than asking. Voice chat was infrequent, maybe 1 call a day if that. Output wa affected more by voice chat/face to face chat.
6. I get more done around people who are also getting things done.
