I'm familiar with the streaming culture. I'd consume and study at the same time.

The voting inside chat, I think, is possible. Talk to the Peakd crew. I'm not sure but they might have a solution.

I can't help with the development side of things. I thought of a voting widget of sorts but, no clue how to explain it properly or build it. Probably have to work some layer 2 magic there but again, I'm not sure. Something simply acting as post. Maybe similar to how Inleo handles Threads. Might be some inspiration there. Again. Not sure.
