Are there any records available from before this post was made (I’m not just being difficult, I’m trying to make [and later score] my own predictions)?
No, unfortunately not. I don’t know tinychat well, but I don’t think data on that is available anywhere, so the only way to estimate it would be to ask people. (I also keep a list of new additions in the order I met them, so I can roughly say if there have been more or less new people around lately, but this is not accurate/complete/what you asked for.)
What do you mean by participation? How would you measure that?
Mean people-in-chat/hour.
