An introduction / tutorial series?

I know, seems silly, but…
I hated the new forums at first. Hashtags for structure instead of categories? Yeesh! But like the weird rash on my neck, it grew on me. Now I have the opposite problem: It intrigues me and I want to use it better.
Note that I am semi-ancient (I used to wear moonboots! Unironically!!), so it might be second nature to y’all, but if someone made a video or six on getting more out of the new features, I’d watch!
