OwnCast is great but the level of dead data / droppd data afterwards is a terrible exchange.
Per second is 1mb/s up and down stream eating energy away and for static stuff mostly watching someone doing not much... even regardless of crappy topics I don't like even my stuff it would be hard to justify and mostly for the chat sidebar (similar to Jitsi in Audio/Video chat).
#Owncast people have to imagine more of a cost about what they are doing and even allow downgrading quality -
The MASSIVE disposable data and bandwidth I personally would justify even for my own 'best' stuff. (If I have one tomorrow kill me!... but if you do like / hate the idea also do let me know as I was thinking before "live" is better than "text-only" or "unanimated" teaching / education / awareness) so it makes sense even at HUGE GB's of watching we will still watch people on screen - a double edged thing usually not working out well
SUGGESTION: At least make stream resolution selectable @ 140p / 240p / 360p video or audio only since even best talks or DJ we might not want to watch all the time and get back to our own work but would listen in like a radio a bit longer...
Would be hard to leave data streaming like that much like leaving a tap on...
Otherwise just another hole for data to be wasted and burned and apart from 'fun' it might just become another standard between those that don't understand (like having 12MP photos and asking services to given them more cloud space / buying new hard drives when they could just keep 5MP pictures or choose what is 12MP a bit more specifically!)
The cost makes me want to cut off my arm to save the body!
(in this case, save the planet's energy and our own bandwidths per second)
You can measure UP/DOWN data load using a bandwidth tool (yes you would be surprised!)
If you want to see the shit people are trying (fair enough for a bit of testing) then watch this profile to get updates on people streaming...
We could do more educational things better I feel... But then again probably nobody would watch like their channels too!
