Who else remembers when it used to be an insult? I preferred it that way.
Yeah. I remember TL;DR meant wall of text, kinda same way RTFM was used. It was a response to something not a tag to indicate what you were doing. How things change so fast on the Internet.
The new meaning is a lot more useful (in the sense that I find lots of opportunities to use it).
Agreed, I still have insults a plenty in my quiver.
TL;DR: You prefer the old way of doing things.
Funny, I thought it meant...
Too Long; Didn't Read
I thought it stood for "too long; don't read"
Why not use the word "summary"?
I think it's the same reason people write "lol" instead of "hahaha" even though they are not actually laughing out loud.
It sounds like internet speek, it's cooler and more 1337.
To be fair, this is the way language has always evolved.
