Something I'd like to see ... is being able to say "I don't want to vote on this node", which would then let you see the reputation of that node.

Yes. I've wanted a true +=0 vote for a long time. I do personally vote sometimes to see what rep a given node has. It'd be better if I didn't vote ++ or -- if I didn't think the node deserved either.

Another option would be to close voting on a node after a certain period of time (say one month) and show the reputation to everyone after that.

Yes! I was just talking about that yesterday. It'd help elimate the inflation of reps of nodes that have been around a loooong time. I would recommend a period of time longer than a month though; three months maybe.

Which reminds me of something else that would be nice: to be able to see the total vote count on a node, instead of just the reputation.

Yes, that'd be cool, too. (I have a little project related to this coming down the pipe. Stay tuned.)

Of course, keep in mind, I say all this because rep and XP are meaningless things, especially when they don't mean anything. ;-)
