Speaking of Reddit, it seems to be an incredibly noob unfriendly place. I can't count the number of times I went on some subreddit to ask an innocent question, and it immediately gets downvoted or even moderated, with no explanation as to why.

I like how on SN, both upzapping and downzapping cost you something. Even though it's only a little, it keeps things more honest, as far as I can tell.
