Bahahaha! I wrote a blog about Pokemon Go too! Isn't it awesome?! Team Instinct here. My roommate recruited me to #teamyellow and I kinda like that it's the underdog of the teams. :)
I'm level 10, but I only started two days ago. It's definitely addictive! For sure there is yellow out there... when you least expect it.... Any one you're especially hoping to catch/hatch/evolve?
I'm only level 5 and I don't yet know what you're talking about with the teams but I suspect that's because I just got to level 5 and couldn't battle before. :) Soon.
