I did live coding on twitch back a year or so ago, for about 2-3 months. It was nice to get a bit of company working from home on my own sabatical (aka. financial dive) year.

Overall though I don't think it's worth it. You get the usual lurkers that come say hi, and then a bunch of drop-ins that have language questions, stackoverflow type questions, or start rambling about technological choices which eventually distract you from your burning floor todo list staring back in your eyes as deep as the abyss.

Fun though, but counter-productive.
