i'm not specifically talking about this year (since i've no clue what's happening these last 3 or so years), but in the past there were definitely global announcements, so visibility definitely wasn't the problem - and we got maybe 12-15 candiates max most years. from that point, maybe half of those probably went forward and did a good job judging.
obvously like all these things, making them so as many people as possible can see them is better.
Speaking as a judge--while this was in fact the place where my judging was at its weakest, this was not nearly as hard as you're making it out to be. I DID go through games. I do admit I didn't go through games quite as thoroughly as I'd have preferred, but I wouldn't call the judging I did half-assed/poor.
i also wouldn't call yours half assed, but the majority of the time i personally didn't think the level of scrutiny for BOW awards wasn't high enough - as someone who judged them and read a shit load of games, it's a difficult thing to try to read maybe up to 60 games for one award. it usually ended up with 2 or 3 people reading them and a couple of people popping up to agree.
