Too long. Didn't read.

I was reading a neighborhood thread about...well, I don't remember the context of the conversation, I only remember scanning a topic.

One person responded in a couple of sentences, another responded with a paragraph, and a third responded with about a dozen paragraphs. These dozen were lengthy with complex syntax and structure and subordination and right after this post was another one made up of four words:

Too long.
Didn't read.

I found this reply brilliant.
It's my new shorthand.

Be considerate of your readers and listeners: begin with the point.
