Top 50 Ruby on Rails Websites (storecrowd.com)

I don't know where they determined the entries on this list, but I'm 100% sure that A List Apart is running on PHP/MySQL via the ExpressionEngine CMS (http://www.expressionengine.com)... which then makes me wonder how credible the other entries are.

Edit: I did a little digging and it looks like they used to be on RoR but switched over sometime in mid '09... so I guess that explains the mistake.

but... Rails doesn't scale.

Scrolling down those screenshots, I couldn't help but notice how many sites have big, square advertising banners (even if they're of the internal, 'Sign Up Now!' kind) on the mid-to-lower right hand side.

Is this based around some kind of science/statistical analysis?

Not sure about the research that went into this article. It totally missed mentioning Ravelry (http://www.ravelry.com), which is an amazing RoR site that is developed and maintained by a single developer.

Here's another source, ordered by Alexa rankings: http://rails100.pbworks.com/w/page/8815411/Alexa-Rankings

(Not sure when it was last updated, though. The wiki seems to have been spammed quite a bit :()

Anyone else find the social media dropdown that appears after you scroll about halfway down the page incredibly annoying?
