It's popularity is starting to concern me. It's going to peak, get to cool, and then crash. Just like everything. I already can't stand how much the term Strobist is being coined by all these people that want to associate themselves with David Hobby. Like those Strobies modifiers. Or how much people think it's now the official term for using small flashes, as if it's some new thing to use small flashes on or off camera. DH did and incredible job of branding himself, maybe a little too good. All that said, there's a reason why teh blog is so popular. It's hands down the best resourse for understanding lighting.
