I am not a great fan of the bonus for unloading all your votes in a day. Some days, I just do not read enough good posts. even with rewarding good questions as well as good answers. (not because there arent any but because I do not have time) In this situation it is tempting just to throw votes at anything just to gain more XP, but I manage to resist. It would be better just to give out the 75% per vote.

While we are talking about the XP system, I don't like the inherent randomness of it. Just give .75 XP for each vote cast and be done with it. (Yay determinisim!)

If anything I think the experience gained from posting is too much. Experience gained from a post should be soley tied to the reputation that it recieves. Thus useless posts that stay at 0 gain no XP for the writer.
As it is I could go round posting "me too"'s to plenty of articles, which doesn't really add anything to the site, but each would gain me +1 XP.

Overall I think it is good that this site has things pretty much under control, and we can just sit around quibbling about refinements. We probably should make the most of it before we have to spend all our votes -1'ing hot grits :)

As a side point, it is interesting to note people's arguments and compare that to their number of posts :)
