If you look up in the address bar (or down if you’re using a Windows Mobile device) you’ll see that I use the unique domain name extension “.im” in order to neatly make the word pixelswim. I’ve seen other sites do this sort of thing as well.
Here’s the thing: it’s purely for aesthetics in the browser and you’ll only see it while visiting the site. I don’t use the “.im” domain extension on any of my business cards, in my email address or anywhere else I advertise this site, including verbal exchanges. I use “pixelswim.com” and forward it to this domain because it’s much easier for someone to remember and more ubiquitous with what a web address is (here in the U.S. anyway, but it applies to all standard domain extensions).
This is how I think these clever domain extensions should work. Do you agree?
P.S. this doesn’t really apply to extensions that are full words in themselves like “.audio” etc.
