The biggest thing about the throbber is that by now it's *so* ingrained into people that it means "loading" or "please wait" that you could really screw with people's heads if you used it inappropriately. Not that I would do such a thing.

[edit: At this point in the original comment I had put a reasonably authentic-looking "Loading rest of comment, please wait..." notice complete with a throbber. Although I took care to make sure it was somewhat easy to recognise that it was fake, given what I'd said above, I decided to remove it in the end because it just played on my conscience too much. :/]

Please don't kill me.
