I've noticed that a lot of puzzles that I've been posting (and a few others) are word problems. Does this merit a tag, compared to, say, questions about sudokus or Rubik's Cubes?
What unifies the Sudoku and Rubik's cube tags are common methodologies and algorithms, which serve as a helpful classification for questions. More specific tags can work to classify these problems.
I'm not sure word problems as a whole share this type of classification, however. While this would potentially be useful, I toss my vote in negative.
Just my two cents, though!
