Who types URLs or looks at them? If you write URLs in an email, print them on a business card, put them on a poster, say them in a conversation, or basically need anybody who isn't already using a web browser to go to your page, you type URLs and look at them (or hear them). Hearing is the worst offender.

- Hey there, you should check out this really cool site/post/app/thing!

- That sounds nice, where should I go?

- You go to uh.. googledrive dot com slash host slash zero capital B ehh... forget it.

There is a reason that facebook gave their users vanity URLs, and twitter user URLs are so minimalist, and people pay millions for domain names. A shorter URL is more useful and hence more valuable.

Having the option to point your own domain at the folder would be really nice, actually, and put this on the same tier as Github Pages and S3.
