Yup, I do own a few! :)

That's very true that they're mostly obscure domains, but that doesn't make them any harder to buy. Most domain registrars will show you all or most possible TLDs that are available for your domain.

You are right though, it is something that would be harder for users to remember than a traditional TLD, but then again, it's only four letters... so I don't know. But still, I use mine for configuring servers or whatever other little thing I need (making incredibly short hostnames, email addresses, URLs, etc.), so I figured many others would do the same... but I guess not.
