Right now there are 300 live viewers watching people in twitch Game Dev.
And going to the website of liveedu.... well it is aweful hard to find a list of live streams ordered by number of currently active viewers. It almost seems like they are trying to hide the number of active viewers, perhaps because they are so low.
The closest thing that I found to a list of active live streamers shows me that there are 2 streams running right now, with a total of 15 users watch.
It could have changed within the hour, especially if - as others said - it's a morning routine thing. In that case almost all users/streams could stop across a one hour period.
