Nice list - and I assume very welcome for newcomers. We are so used to those abbreviations that we sometimes forget newcomers are unfamiliar with them.

One thing I do find funny, though: TLDR - I always read that as 'too lazy, didn't read'. It's good to see that i'm not the only one who does that. It's actually : too long, didn't read... but I prefer the one with 'lazy' in it ;0)
