This is pretty much where I’m at.
Discord is where tight knit social circles are.
Youtube is where I watch content from large creators I follow.
Lemmy is where I can follow public discussions about a variety of topics.

I have a Mastodon account and I like the instance, but it unfortunately fails to really deliver any of the 3 things I mentioned above.

I have a personal project that was getting big and unruly, and I’m so happy I learned how to use Docker and converted all the little pieces into their own repos and containers.
That being said, I totally went down rabbit holes that didn’t end up being helpful, like setting up my own CI/CD or trying to learn Kubernetes. They were totally overkill for me.
