Yeah overall some theme diversity. Would also be interested to know the median Elo rating by tag - since that'd serve a good sort of table-of-contents of order for people to learn chess tactics. What is also pretty interesting would be a (fuzzed) per-tag Elo rating on the user - so they can see which themes you are good/bad at relatively (for example, if you constantly get problems on Trapped Pieces wrong your rating on those problems would be lower than your average Puzzle Rating).

Yes, the rating differs by theme quite a bit. +-------------------+------------+ | theme/tag | mdn_rating | |-------------------+------------| | Opposition | 1725 | | Passed Pawns | 1494 | | Rooks on Seventh | 1408 | | Pawn Endgame | 1353 | | ... | ... | | Smothered Mate | 549 | | Stalemate | 533 | | Mate in 2 | 436 | | Mate in 1 | 399 | +-------------------+------------+ I also like the idea of showing the user's +/- for each theme. Though the data for some themes is better than data for others.
