Sorry, I guess I'm old.

On one of my questions, I was asked for the "TL;DR version".

What does that mean?

I wish I didn't know what tl;dr meant; it would mean the sites I frequent aren't infested with impatient children –  Michael Mrozek Nov 23 '10 at 20:32
    
"Too old" in this context means "to have an attention span longer than 0.1 ms and thus be able to read a block of text that's longer than 140 characters." –  MPelletier Nov 23 '10 at 20:34

Hmm... Old fogey though I am I like to see a slightly-longer-than-the-title summary on questions that require a gray wall of text to adequately describe so that I can decide if I want to read the whole thing. –  dmckee Nov 23 '10 at 20:49

I had to google for TL;DR the first time I saw it too (a few months ago) and I'm only 25 –  Mark Henderson Nov 23 '10 at 23:12
    
Henceforth I shall name my documentation files that. –  mario Nov 24 '10 at 0:47
    
For long time I've thought that people writing that have problems noticing that escaping HTML entities didn't work –  Donaudampfschifffreizeitfahrt Jun 12 '13 at 10:11

Too Long; Didn't Read

It means they want a summarized version.

Thanks. I guess that means a lazy reader who couldn't read a page of text. I would welcome someone creating a "summarized" version that could still be answered. –  John Saunders Nov 23 '10 at 20:07

@John - try "Need SQL Help! URGENT!!!" –  user27414 Nov 23 '10 at 20:08

@JonB: I'd try that, but the only possible answer would be the URL to Books Online. –  John Saunders Nov 23 '10 at 20:09

@John Saunders: It doesn't necessarily indicate laziness on the part of the reader. It could easily indicate laziness on the part of the questioner. –  David Thornley Nov 24 '10 at 15:38

@David: but since the questioner is me, that is certainly not the case. –  John Saunders Nov 24 '10 at 18:20
    
So, it's a comment, and answers with TL;DR should be flagged as NAns? –  Donaudampfschifffreizeitfahrt Jun 12 '13 at 10:09
    
@ŁukaszLech, if that's the only content of the answer then yes. If someone provides an in-depth answer then includes a tl;dr version, that would be fine. –  Brandon Jun 12 '13 at 14:39
    
@Brandon OK but generally, if someone writes TLDR, it means, they didn't ever read the answer? Or it's just bantering with OP? –  Donaudampfschifffreizeitfahrt Jun 12 '13 at 15:00

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.

did you look at the question? If you can think of a simpler way to explain what I needed, I'd love to know it. I'm not an expert on relational database theory. –  John Saunders Nov 24 '10 at 18:21
    
@John: When I first saw the question, I didn't read it. It looked forbidding, like a wall of text. My first point is that it looked unappetizing, and the "tl;dr" commentator was pointing that out. My second is that you are asking unpaid people to help, and accusing them of laziness strikes me as being overly demanding and ungrateful. I'm not saying anything about the original question (and I'm glad you got useful answers), since this wasn't a question like "How could I improve my question so nobody thinks 'tl;dr'?" –  David Thornley Nov 24 '10 at 19:10
    
my point is that I don't think the amount of text is excessive for a question of that nature. I could be proved wrong by someone showing me a way to simplify the question. I know the answerers are unpaid (otherwise someone owes me money), but if I'm right that it's not too much text for the problem, then nobody looking at the question should think it's too much text. Please show me where my reasoning is wrong. –  John Saunders Nov 24 '10 at 19:58
    
@John: Empirically, I was turned off by the appearance of the question, and so apparently was the person who posted "tl;dr". I don't think it's the amount of text, but rather the lack of an easily distinguishable summary. (Yes, I know the first paragraph is one, but that's after reading the question.) Setting those off with "Summary:" and "Examples:" might be all that's needed. As far as your reasoning being wrong, the problem is that it's reasoning as opposed to observation. Empirically, something is unattractive about your question. –  David Thornley Nov 24 '10 at 20:26
    
I was hampered by not knowing the correct terms for the "key" and "more than the key" columns. –  John Saunders Nov 24 '10 at 20:34

There are people who seriously say "teal deer"? –  Grace Note Nov 24 '10 at 20:35

@Grace: there are people who put one inch diameter holes in their ears. I saw one last week. Eery. –  John Saunders Nov 24 '10 at 20:42
