Subject: Two column proofs

I feel that two-column proofs are important in geometry, but they should not be the main component. Flow proofs are interesting, as a paragraph proofs. It is the logic of an argument, not the structure of the proof, that is important. Proofs in geometry should always be included in the curriculum, but they should be only part of it.
