Use American English

[agrimm]

If non-English languages should be avoided in code, should non-American English be avoided as well?

I think this makes sense, but I haven't done coding in a group of people, so I don't know what other people think.

# bad
attr_accessor :colour

# good
attr_accessor :color

My opinion is that this is not ruby-specific codestyle rule, it's more like a common rule for any programming language so this guide isn't a right place for that.
Moreover I think that these rules can be omitted as well https://github.com/bbatsov/ruby-style-guide#english-identifiers https://github.com/bbatsov/ruby-style-guide#english-comments

That's a good point. I withdraw my +1.
