Matthias Ott wrote this article called “Make it Personal” on CSS-Tricks.

On your personal website, you own your work. You decide what and when to publish. You decide when to delete things. You are in control. Your work, your rules, your freedom.

He particularly emphasizes that one’s own website can be an excellent playground for learning and trial and error:

Your personal website is also a wonderful playground to tinker, prototype, experiment, explore, and learn about web standards and new technologies by experience. Want to improve your accessibility skills? Want to learn CSS Grid or try out variable fonts? Want to implement your first Service Worker or fine-tune the performance of your site? Your personal website is the perfect place for that!

But what am I sharing this link here anyway, I talk about personal websites and blogs way too often. 😉
