This is an example of an ad I saw on Google just now. Funny thing is that I was searching for "render partial" and not "render :partial".. yet I bet "render :partial" is searched for more often because that's the actual syntax in Rails for rendering a partial. This demonstrates Google sells popular searched keyword lists to eBay, and they blithely have Google ads for those keywords.

I don't think I've ever seen any "Render :partial"s for sale on eBay :)
