I know that writing style is standardized in magazines. I'm not sure about coding style, though I'm sure it's standardized in books. There's not the same style in every book, but within a given book, the coding style would probably be consistent. Doing the same on PerlMonks would be in keeping with the standard for code conformity set by the non-electronic media. There isn't much of a standard on the web. I don't know of another message board with a significant number of full length scripts. But more important than that is setting a good example with the posted code.

There are a lot of people on this site contributing a lot of content for a lot of different reasons. Some of the code in the snippets and code sections may be there for pedagogical purposes, but most is probably posted with only the intent of sharing the code. Trying to enforce a particular style on those sections would be like trying to enforce a coding style on CPAN submissions. Shall we also set up a GrammarTidy for non-code content?
