Dunno. Doesn't matter. I just think it's a bit weird that so many people care what others waste time on. We all have our things that we like to do that don't make a lot of sense to other groups of people.

Edit: See, even I am doing it there, thinking it's weird that other people waste time on caring about what other people waste time on. If you want to waste time on trying to convince people that they should be more productive, and that makes you happy, then go for it!

Live and let live.
