I don't agree with this list. Spot.us, for instance, has completely non-standard controller code that goes against widely accepted conventions. I also haven't looked at lovd by less in a while, but last I checked they relied on widespread monkey patching of core Ruby and Rails classes just to avoid writing a couple characters.<p>Also very notably absent is gemcutter (<a href="http://github.com/qrush/gemcutter" rel="nofollow">http://github.com/qrush/gemcutter</a>) which is actually clean, modern and adheres to conventions.
