CommandShift3 is “like Hot or Not for web design”.
(In case you’re wondering, the name comes from the keyboard shortcut to take a screenshot on an Apple.)
On CommandShift3, you are presented with the screenshots of two websites side by side. If you click the screenshot of the site you think looks best, the page reloads and you start all over again. It never ends.
There’s a best & worst page where the winners and losers are gathered up, and you can browse winners by tag, week, or month, so there are plenty of options if you just want to look around for some inspiration.
(And if you’d like to check out and hopefully vote for DidntYouHear.com on CommandShift3, go here.)
