I like to just keep an eye on the new section, lots of stuff to sift through but it feels good bringing up a good post that was at 0.00 even if its just a meager $0.10 vote from me.
I find comments almost never get noticed or upvoted so I dont bother putting much time into commenting anymore.
I also like to sift through the mass comments on popular posts and upvote the good ones to move them to the top (rather than upvoting the post, since it is already doing well)
I love the new section also!
