Well, in the past, I've always diligently read everything on the list - after having knocked out those stories I know that I'm not going to be nominating.
This year, I simply haven't had time to catch up with 99% of what's eligible and with time running out it looks unlikely that I'll catch up.
So, I've been pondering this very question all week. I am going to read as much as I can get to over the next couple of days, but I've pretty much decided that in the end it's better if I at least nominate what little I've read and feel are deserving of recognition, than not nominate at all.
It's not perfect and I'm less than happy with it, since it undoubtedly means that I'll miss out on nominating a good story because I never read it in time, but this year it's simply the best I can do.
