i really enjoy the new layout, it gives me stuff to browse in my downtime
i also think the up/down voting system is cool too and a good way to bump good content and filter out the rest.
I found my way to site discussion today to make a suggestion about the up/down voting. If you vote a piece of content up or down and then change your mind, there is no way to retract your vote. For instance: A video is rated at +20 currently. I come in, start watching and see something cool and upvote it, putting it to +21. Then by the end i change my mind and dont want to upvote. With the system working how it does you cannot simply retract your vote and put the video back to +20, you have to leave it be or down vote it moving it down to +19.
Just a thought.
