I use Couch to develop one of my activities, which consist on selling painting reproductions through internet, this one's in French: http://www.tableaux-sur-toile.com

I use Couch to manage this site, which make it very easy, and SEO friendly, especially with the great pretty URL tool.

Just started, but I will be on google first page soon, and it will be partially because of Couch.

Great software, it changed everything: finally a user friendly CMS. My clients are ecstatic...
