I'm not sure that AM do get less votes than they deserve. I personally tend not to downvote AM posts as quickly as I would named posts (unless they're particularly obnoxious), but I will upvote stuff regardless of the author.

As far as points go, I stopped running out of votes regularly just before the recent XP change, have started again now and hope to stop again after rising a level or two. One thing I've noticed about this discussion that people who are a bit higher-ranked are not complaining about running out of votes, whereas people with lower ranks seem to do (well duh! ;-). If the goal of PM were to make every participant happy it may be better to change the XP system once again, so that there's a high rate of vote-increase in the first levels until one gets to 20, and then slow down (say one additional vote per level). That being said, I don't think it's a big deal and I'm happy with the system as it is :-).
