I've always wondered people like using a Gem. It's better for me to just write in a bootstrap.css file in my assets folder and add it to the application.css tree.

Why add another point of failure on your site?

I've been using https://github.com/anjlab/bootstrap-rails for http://www.photoficient.com (https://github.com/frabrunelle/photoficient).

I would definitely recommend this gem. Yury, the maintainer, updates it pretty much every day.

I haven't had a chance to try it yet but I found this: https://github.com/diowa/twitter-bootstrap-rails/tree/bootst...

It's a fork of the twitter-bootstrap-rails gem.

Edit:

There is also this: https://github.com/jlong/sass-twitter-bootstrap/tree/3.0.0-w...
