i love experimenting with things on my company, because then i get to really understand the impact notches through my clients. I shut things down pretty, pretty drastically for things that i know aren't working im and so if i'll go in to new companies, they i have data on all the things that they've been doing. Have you ever justike, shot oneo, one part of the engine off completely, just to see what would happens? Or have you not ever done anything that radical?
