That sounds like a fairly wasteful idea. It'd be far easier to request them as quotes from a qotd service, but what's the problem with that? The extra layer of evaluation is missing. Mind you, it's a safe layer of evaluation.

The minute you involve web fetches of any kind, you either lose the layer of evaluation or you expose your entire system to the server; You essentially become part of a botnet. Don't trust scripts that use "automatic fetching from HTTP", particularly in conjunction with $eval, $(), timer, /flash, /scid, /alias, $read without the n switch (as in my script), etc. They're a real potential security risk... It's your credit card ;)
