I do katas every week and think they are great for both reinforcing good practice and helping you get over rough patches in your understanding of a language. That said there are quite a few katas out there that are either trivial or merely puzzles to solve. The former are great for beginners but pointless for anyone else. The latter are fine if you are doing them for the same reasons you would do a crossword puzzle but they are probably better avoided if your goals are more practically oriented. The hard part is wading through the chaff to get to the wheat.
