I'm super proud of the fact that my website has no tracking, no cookies*, no registration/sign-up and no ads. It's rare in today's internet, and that's a shame.
(*there's 3 necessary cookies on the frontpage due to the mailing list provider, SendFox, and its captcha)
@kenney That's something I am super proud with my website, too. Made sure to make it as primitive as possible so I could get away with 0 cookies. At this point this is more important to me than most other features. :)
