I obviously don't agree, but it is worth noting that comparing typographic conventions for English with typographic conventions for code is not a very good idea, to me. Especially when we're discussing a language with semantically active whitespace.

A 100 character line might only see 15-70 characters of active use.

While this is a fair point, pylint bumps the limit to something like 100 characters, and you can split deeply nested logic into separate functions with ease.

HN has ~200 char lines and I find it easy to read long bikeshed arguments.
