Sodor Mail Car w/ factory error - fix or sell?

TL;DR stands for "too long; didn't read". The phrase, or more commonly the acronym, is often posted by a reader of something on the Internet that decided not to read something they thought they would be interested in or willing to read because it turned out to be too long to keep that interest or for their time. The same is now used just as often to indicate a summarized version of an Internet post so that people know that it is there and don't need to read all of the details if they don't want to and/or don't have the time to.
I can't get a picture right now but will later if I can remember
