Sorry, I guess I'm old.
On one of my questions, I was asked for the "TL;DR version".
What does that mean?

It's an abbreviation for "Too Long; Didn't Read".
What it means on SO is that somebody didn't feel like digging into what you wrote for all the details without more guidance in the way of a summary. Since you're asking for help, and you're going to get it from unpaid volunteers who do it for their own reasons, you might then consider getting the question into a more readable form.
There are people on this site who get ticked at being asked to figure out a question when the questioner didn't seem to care enough to be clear and explicit. Usually, they'll go away and not pay any attention to your question. Posting something like "tl;dr", while perhaps a bit rude, is a useful suggestion.
Fundamentally, two things will happen to any unpaid Q&A site. Either there will be some action to keep the quality of the questions up, or the people who actually know things and are useful go away. We've already lost a really good C++ guy, apparently fed up with question quality among other things.
