I keep this list curated, so I confirm these people are doing mostly coding streams - and in future steps, I'd like to add more platforms :)

I started out last week with like five people, and only twitch people kept writing me so far :)

It's a good discovery tool. I actually searched for devs doing live coding in twitch few days back but barely found anyone.

I find list useful, I was trying to find such streams earlier with no luck. Unfortunately I only found 2 dead accounts by searching for programming, maybe it is just I am not that familiar with twitch.

Here [0] is a list of currently live streams who have categorized their stream as programming. At time of writing, there's about 50 live streams.

Same reason we use link sharing sites like Hacker News, and Reddit... You don't need to search.
