I build systems (devshop/aegir) that create and destroy websites on the fly.

If I'm working on a feature related to that process I could create and delete a dozen or more arbitrary domains in a day.

I also know plenty of web development teams that are less technical and could deal without manual hosts file tweaking on a daily basis.

I also use multiple computers. With this domain, I never have setup Dnsmasq, never have to edit a hosts file, never have to edit DNS.

Being obsessed with automation and efficiency, anywhere I can save a few seconds, I will.
