There are so many nice and interesting folks around, I can't possibly name them all! I'll make an exception for @johncarlosbaez, who got me to learn about Coxeter-Dynkin diagrams, and many other cool things.

I'm picking John, because his threads tend to attract lots of mathsy and theoretical physics people you might be interested to follow. And also, because John is a friend, and I think especially you should check out his writings. I'm sure you'll find a lot of joy there! Maybe start here:

I know you like mathsy graphics, @johncarlosbaez, and I have a feeling you two might enjoy knowing each other!

We met at and had fascinating chats about geometry and other maths. Do have a look at his youtube channel for some very cool explainers packed with eye candy. Like the latest, about Coxeter-Dynkin diagrams (link upthread)!

Or this one about spherical harmonics:
