Yep, what they offer and results is what counts. But the dn is an important piece of the puzzle. And I'm not seeing the connection with the new name, other than it being an acronym. I don't know, maybe Dan will grow on me. I just think, sometimes shorter is not always better. Dan takes away from the descriptive DN suited to what they offer, and relegates to a boring LLL. Albeit "undeveloped" has a negative connotation, the site and services completely turned it into something positive.
Your DN should have a great, visible connection to your brand and message.
