Replying to Why do we still not have up and down votes for posts?

(My standard disclaimer for any time I ask a question like this in this forum: I adore this site and it's beautiful, much nicer on the eyes and more functional than most any other site i know of. i appreciate the work you guys put into it and i have almost no complaints ever)

anyway...why do we still not have up and down votes for individual posts? i know you admire reddit's system, mr bishop, so why havent we implemented this yet? each post can be upvoted or downvoted by everyone, so GENERALLY, good, informative posts get upvoted a lot, bad ones get downvoted a lot, and the reader can usually get a good idea of how much stock to put into any given post by looking at its score. this also eliminates millions of quote + "this" posts to back up good posts

this also means that users' karma scores can actually mean something because they simply are their net upvotes, rather than a one-time 1-10 score. if a post has +134 upvotes you can be pretty confident that it's trustworthy... and if a user has thousands and thousands of upvotes, you can reasonably assume he's a pretty good member for the most part

so why havent we done this?

PS- one more thing-- if we do this system, let's skip the part where a post is hidden if it gets 5 or more downvotes. that is RETARDED
