Partly because my co-founder has a strong OpenID background (he wrote the first Drupal 5.0 OpenID module), and partly because we didn't want to create Yet Another Account for people to remember.
We are adding the feature to create a new account (which happens to be an OpenID account, but users don't need to worry about how the backend is done) from within the site, so anyone can register without an existing OpenID account.
I meant short time procrastination as an indicator of sleep deficit. It's the best indicator you sleep not enough. You should pay some bill today but you can't find enough energy to do it (you can also feel strong aversion to do it) so you move this task and three other tasks to the next day. Ask yourself if this already happened.
There are some techniques by ex. some very intensive buddhist meditations (you can't perform in normal daily life) which can help you slow down your metabolism and so also need for sleep and eat without impact on your health, or techniques how to wake up exactly at 7AM (it's the best time IMO) without alarm clock.
