Before you get too excited, don't forget about timezones. I'm guessing you finish school, 3 - 3.30. Which is 11pm on the West Coast, 2am on the East. It makes catching up with interwebbers slightly more difficult... Sorry v.v
Weekends? If you can get on in the mornings some people are already home... If you stay up late enough (well, not that late really), sometimes someone will stop by during their mornings...
