The common dilemma I face with this site is how much time to spend on it - or how much time spent doing things related to it (image hunting, sitting on Skype, etc).
I'd say probably 5+ hours per day during the week and more often than not 0-1 hours per day during the weekend. The way my schedule is set up atm with school and work, I have 3 hours of dead time in the afternoon from when I finish class before work starts that I usually spend making posts on here/doing homework. And my job is a stand around for 8 hours and do almost nothing (I work at the school) so I have a lot of time to dick off on my phone, so I'm usually perusing the random stuff on here and doing other things on the net.
But since I'm gone 12 hours a day during the week, my weekends are usually jammed with a bunch of crap I don't have time for during the week so I hardly have time to make meaningful posts here. (I'm on my phone atm, actually. :P)
edit: and lol oops i clicked the wrong choice on the poll. :x
I used to be two to three hours a day, not just writing or reading but researching and exploring ideas for my characters. These past few months with band season, I'm lucky to have two hours a week, and some days I might only have five minutes to lurk. I'm gone every day for practice, and I've got rehearsals, games, and competitions every Thurs-Sat, sometimes Sunday as well.
Next week is my last week in the season, though, so come November I should be a LOT more active and consistent/frequent in my posting.
Well, up until recently I was on quite a bit. It was mostly reading threads or looking stuff up on Wookiee for look ups and whatnot.
But being busy IRL, and trying to focus on some stuff limits my usage a lot more. On average now it's probably 3 hours tops, weekly. Used to be double that at least.
My time here tends to fluctuate a bit, but I would say a fair minimum for me would be anywhere between 1-2 hours a day. That's not to say I'm always posting or being constructive though. Mostly it's just lurking, looking at what I should be doing, then ultimately kinda... not doing it.
On days where I'm feeling particularly motivated though, I can spend upwards of 5+ hours on the site either working on posts, researching for stuff, or talking out potential character plots with others on Skype.
It tends to depend on the day for me, really. And weekends are generally a no go. Just because I feel like slacking off.
