Anyone who's interested can find an in-depth explanation of !-methods here: http://dablog.rubypal.com/2007/8/15/bang-methods-or-danger-will-rubyist That post talks about the Ruby conventions, as delineated by Matz and practiced in Ruby itself. Rails doesn't follow those conventions but, with all due respect to the Rails team, I wish it did :-) and I strongly recommend following the conventions when you choose method names in your own code.
