A good idea, and one I had myself recently. Some suggestions: I know none of us like "the algorithms choosing", but I think we can do better than alphabetical order. Number of clicks you see (popularity), or number of inbound links google tells you about would be good. I also think you've gone to great effort, but it's still very light in some categories. I hope you keep going - what's your data source? Are you track…
I think equally important is algorithmic transparency, that is, that the algorithm be publicly disclosed (although I think simplicity is a component of transparency: if you just dump a huge incomprehensible algorithmic mess somewhere that's not very helpful), so that you at least know what you are getting into, and better yet have some ability to choose and make educated critique of the current state of things (i.e. does the algorithm just maximize engagement like a slot machine? or does it optimize for some kind of helpfulness?).
