I love this typeface very much. Initially I used it exclusively for the Berlin site meditieren-berlin.de. The reason is, FF Karbid is based on storefront lettering in Berlin, so I found and I thought it fits well for a site covering an aspect of Berlin.
Later the publisher of the Buddhist magazine Ursache\Wirkung (Austria) suggested to run such a service (a positive list of safe meditation groups) also for other towns in Germany, Switzerland and Austria. The editorial office of the magazine collected the data for 25 towns. Then I set up the main domain, www.meditieren.tips, shifted the Berlin site to a subdomain and currently we have sub domains and offer this service respectively for nine towns. Sixteen (and in the long even more) sub single page design sites (or micro sites for each town) have still to be set up.
The last two screenshots show how they perform on mobile devices.
