As our code base is growing, I'm noticing some style variations that affect readability. Nothing scary, but this is probably a good time for everyone contributing code to have a look at
http://www.caliban.org/ruby/rubyguide.shtml#style
In particular, keep an eye on line length, indentation, and the use of whitespace. This has a huge impact on how quickly someone can scan an unfamiliar section of code. For a project like ours, that can be the difference between spending half the code sprint trying to understand how something works, and digging in and getting work done.
Thanks,
