Whats going on

I haven't really been here for three years and I am poking around trying to remember how to use everything. Anyone want to fill me in? Whats this Tron thing that keeps popping up? Whats the name of the other thing like Steemit that forked off from here that I should also log into or something ?? How do even power up or trade on the crypto market or do anything?
I cant remember! I kind of feel like blogging again. How do I remember how
