This is really cool. It’s also a really important demonstration of your website is your home so you can do whatever the heck you want with it, and you should.
Dave has opted to roll out a subtle daily colour change based on a hue rotation and what day of the year we’re on. Sure, it’s not perfect, as Dave rightly mentions, but it’s theirs. With all of the changes to Big Social™ recently, your content is even less safe in these walled-gardens than it already was.
One thing Big Social™ can’t touch is your website. Heck, you might even get to learn some cool stuff, just like Dave did, in the process. I also need to heed this advise myself, so this little post is a message to myself too.
