Good ideas and conversation. No ads, no tracking. Login or Take a Tour!
I would encourage you to follow users and tags because I do think it can enhance the experience, but unlike Reddit, it's only going to be an enhancement instead of potentially a totally different view. (I have subscribed to so many subreddits and un-subbed from others that my front page is nothing like the regular Reddit front page. I even missed a lot of the Ellen Pao hullaballoo.) I like to browse global as well to see what I have missed. Chatter is fun and useful if you are looking for conversations, you can see what others are chiming in on.
