You are originally subscribed to all the subs so that you can go through things you like and don't like and decide with whether you wanna stay subscribed or not. I guess it's a better way of finding new subs all the time.

I actually like this a lot. This is a cool feature.

. As for karma, the upvote and downvote has gone and is instead replaced with 'funny' and 'interesting' instead. I think this is used to stop people from downvoting things just because they don't like it, which was a problem with Reddit. This way, you can sort posts and comments by "funny" and "interesting". It is reccomended you use the debate pyramid JPG when debating or discussing with someone too. The only thing different here is the no-pornography rule and discussing of illegal vendors I believe, though Gore is allowed.

Ohhhh, ok. So basically there's no "karma" in a sense, it's just funny and interesting. I like that. So there's really no "downvote" in a sense. That's a cool feature
