MicroGems: five minute RubyGems with Gists

This removes discoverability of what could be useful (if small) gems. At the very least, these could be made into full repos on GitHub with READMEs so they're relatively easy to find between GitHub's own search and Google.

What a cool and elegant way of publishing a tiny gem!

However, I will say that I personally prefer to stay away from gems like this, as they add indirection, and make projects confusing for new devs.

I would say that

  bang :calculate_score => :score

is clearly worse than

  def calculate_score!; update_attributes!(:score => calculate_score) end

Sure, it is longer, but any ruby / rails dev will understand it instantly, and I'll take a few more chars for less indirection.
