With all these new features, it's hard to know what button does what, or really tell what filters and tags mean. For example, what's the difference between "Popular" and "debated"? What tags should I use on my topic? What should I follow? What's the difference between unique id and display name? &c... I'm just wondering, where's the manual to all this? And if there isn't one, we need to make it. It's a lot easier to think poorly of something you just don't understand... ...especially if it isn't black.
