Honest question. why use 127.0.0.1 instead of 0.0.0.0?

EDIT: Now I've read the discussion below regarding this matter. No need to answer, I guess. I asked before reading all the comments, sorry.

Assuming you meant why not: "Using 0.0.0.0 is faster because you don't have to wait for a timeout. It also does not interfere with a web server that may be running on the local PC."

He said he used 127.0.0.1 for google analytics. I was asking why he used 127.0.0.1 and not 0.0.0.0, exactly for the reasons you wrote. Sorry if that wasn't clear.
