I try and keep a very verbose Rails Gemfile so any new developers working on my startup can very quickly understand what gems are installed, why they're installed, and the value they add to the project.
I also use my Gemfile as a bit of a todo list when I find smarter or faster gems, or just new cool things that I want to try out. I thought I'd release a copy of what it looks like if you're interested.
