This blog is inspired by Simon Willison:

A TIL—Today I Learned—is the most liberating form of content I know of.

Did you just learn how to do something? Write about that.

Call it a TIL—that way you’re not promising anyone a revelation or an in-depth tutorial. You’re saying “I just figured this out: here are my notes, you may find them useful too”.

You can read about Simon Willison’s approach to blogging in his posts “what to blog about” and “my approach to running a link blog”.

Lia Wälti’s tips: “Drink tap water, enjoy the fresh air, go out a bit - it’s really nice!”
