Discourse seems to rearrange the categories on 301 Moved Permanently based on activity. I find this contrary to my perceived goal of the page: to make it easy to find what’s going on in each category.
Consider that I’m a guy who likes to keep up on UX and DEV, but don’t care about the rest. It’d be really handy if I could rely on Discourse to keep those two sections in the same place on the screen - that way I could easily find and use them.
When the categories move around, it forces me to read and think every single time I view the page. Reading and thinking slows me down, and gives me the feeling that I’m not really in control of the task at hand. Think how much of a pain it would be if “Latest | New | Unread | Read | Favorited | Categories” moved around every time the page reloaded!
