Because he doesn't want submissions or comments, he wants saved posts, which is really different for me, at least, and I assume for most of us. I've submitted 8 posts (only one of which went front page) of which naturally I didn't upvote any, because I can't. I've upvoted 135 posts ... which is way more than I would have thought, actually. And I've made roughly a thousand comments, which I would estimate would be on maybe 500 posts (because I don't normally get into extended discussion, so I'm guessing I average out to maybe 2 comments a post) - and the posts I comment on are not necessarily those I upvote, because I usually forget that you can upvote posts unless I really like a post.
