Mmm-hmm. Honestly, I (and I think anyone else who's ever attempted to run a site before) can understand how difficult it is to do anything at all. The fact that 5MV is so large and has so much content is inspiring, if anything. And so what if you coast sometimes? Doesn't everyone?
Like other people have said, I think we'd just be happy if you reminded us you were still around every now and then. You're the only one beating yourself up--it's not the end of the world if you don't have content up all the time.
And no one's going to turn rabid on you. Unless of course we all run out of pie.
