On Sunday I combed through Twitter and fished out some links that seem useful at the first glance. I have not read them closely yet, only scanned through but I just want to dump everything I found here, just in case:

SL / API	Links
WGSL / WebGPU	Okay Dev article about WebGPU
WGSL / WebGPU	React Three Fiber WebGPU Post Processing (probably just a set up with no WGSl involved)
WebGPU	Interacting with meshes in WebGPU
TSL	Editor that generates TSL code
TSL	Youtube tutorial of Yuri Artiukh (I actually follow him nearly everywhere but did not get a chance to use his tutorials)
TSL	2D Clouds in TSL

I noticed that Okay Dev use Megazoid font that I used for my NailBro project during first year, so I already trust them.
