Cool links are a collection of interesting things I find around the web. They can range from fun dumb websites to deep thought-provoking essays, or more commonly something in between. The feed here updates frequently, and I compile everything into a blog post on the last day of each month.

Building up a weekly routine to organize things has also been a good change, as I don’t have a lot to do at the end of the month when I’m putting this post together.

I haven’t tried these tips in practice yet, but hopefully I’ll have a neat idea I can use them on soon 👀
This article talks a bit about the Netstuck effect, you when feel forced to use a service or platform just because everyone is there, and how that’s different from a monopoly.
As someone with no commercial social media accounts, I relate to this a lot. And even though I can live without a Facebook or Instagram account, I tried not using WhatsApp in Brazil for a couple years and just had to concede at some point, because there’s just no way of getting in contact with anyone (especially businesses) in here without it.
This game tests your knowledge on JavaScript’s Date class. It’s funny because it’s sad.
