Mad props? Blog? WTF?

Sorry, I didn’t get the memo. The last one I know, the first two I don’t. Kudos in advance to any, much more hip, Dopers who can explain what “mad props” and “blog” refer to and where these terms come from.

Cripes, I’m feeling old these days…

“Blog” is short for “weblog”. Writing a weblog is “blogging”, and would make you a “blogger”.

(via, weblog resources and Blog History).

“Mad props” implies paying compliments or giving respect:

(via NetLingo).

Proper Respects = Propers = Props

Props + Mad (an intensifier) = Mad Props
Web Log = Weblog = Blog
