Mainly reading threads here :) I make a stab at looking at the top headlines. There's a pattern in a headline eg. Mentions of GC, datalog and so on which I flag.

The exceptions are Composita and Maude. Composita is off the back of Oberon, which is one of the smaller language-based OSes. Maude I found on a keyword search around formal verification- I'm looking to build a new language so interesting stuff keeps coming up when you go down the rabbit holes ;)
