I while ago I saw mention of the response to a lengthy item of "tl;dr" which stands for "too long; didn't read." It's one thing if something is genuinely of excess length and skipped over - but why post any response about it?
A few minutes ago I saw a fairly short posting, all of 42 words (even with all the punctuation and spaces it's within the 140 character limit of Twitter), get the the "tl;dr" reply. Someone responded to that with I usually translate it as "ta;ri" - "too apathetic, remained ignorant". Yes, that fits.
