Be honest, do the maths, how much time do you spend on forums
1 - Less than 1hr a week
2 - 2-5 hrs a week
3 - 6-12 hrs a week
4 - 13-24hrs a week
5 - More than 24hrs a week
I dunno how ya'll find the time! You could spend 4hrs a day here and still only scratch the surface... and this is not the only like place on the interweb!
I'm sure there are a bunch of you who manage much more than that.
I'll go for months without checking in, but every now and then i'm drawn for my own education or interest, or to help others along. I find that once im in the web, its hard to get out.
