I get the rationale for the starter, but the "Yo dawg I heard u like brewing so we made brew u brew b4 u brew so u can add brew 2 ur brew and make it brewier" aspect is a little daunting, since I already have trouble finding time as it is. Sounds like a problem for 2013 FWF, that guy seems pretty on the ball.
I re-read the 'yo dawg' 3 times, and it checks out. That's hilarious and mostly accurate.
Yeast Starters for me are NBD, because honestly, it takes 15 minutes the night before, and you can do it while doing other stuff too. I managed to cook dinner while doing my last one.
And with Wyeast packs, I think it is even more important. Critical, even. Wyeast has the best yeast, it completely changes the profile of your brew, but even if you properly use the smack pack, you run a possible risk of under-pitching in any batch with a OG over say..1.060 (I'm guessing..I'm not that guy who knows this stuff off hand).
Plus, brewing is fun. If you can brew a brew before you brew your actual brew that you use to make your real brew brewier, who says no?
