Honestly, I feel so sad for this guy I want to puke and sob and nap all at the same time. I've never felt more gut wrenching pity for someone I haven't met not living in abject poverty. He's a useful cautionary tale but not a great follow.

Good way to objectively measure the obnoxiousness of your stream. Pretty accurate – the top ten included all the noisy people who I've considered unfollowing in the past.
