I usually visit once around 3ish afterschool, then maybe 4-5ish, then I have dinner and get back on. On the weekend I'm on continous.
(Well almost, from about 9am-2pm then 10pm-keel over asleep I am, for 2-10 I usually go to a friend's house to hang out) During build I'm almost never on, if there was a graph of my activity, it'd show a constant 1-2ish posts per day from the point at which I joined to build, a steep drop to .3ish for weekdays, 8-9 for the weekend, then slowly up to almost 3 for a while, then a spike to 4-5.
