Somewhere along the line, tI;dr lost its semi-colon. So now we see tl;dr or tidr, or TLDR, and however it is written it stands for “too long; didn’t read.” It has become the way in which to say ‘Here is a summary of what is long and complicated to read and absorb’. Eventually, even this short explanation will be too complicated to spend time on, and we will be reduced to grunts.
