If it makes you feel better, I went through the same thing. So badly, in fact, that my Meta rep has eclipsed my main SO rep.
For me, this is largely due to the fact that my primary expertise is in C# -- an area with tons of competition on SO. Thus, by the time I see a question which I can answer, typically there are seventeen answers already posted. (And another seven come in while I compose mine!)
I took to answering Cocoa/Objective-C questions a bit, but one look at my recent activity will show that I spend most of my time doing "junior janitor" tasks -- editing, commenting and closing. Time well-spent; it's a contribution I can make to the site which helps keep its content clean.
Indeed, I just wish I had enough time to fully clean the place up. But at the rate of content growth, that just isn't possible!
