Posting about online presentations

I organize online presentations about various topics in computing. (e.g. Python, Rust, Go, Databases, DevOps etc.) I also monitor many other channels that have online "meetups". Even if they don't use Meetup to organize them. I am new here and I would like to get the opinion of the community here. Would it be interesting and acceptable to post such events? Would it be considered self promotion if I post about events that I organize, but that features other people as speakers? Should these post be one post per event or lists of events. eg. "Online Python events in the next 10 days"?
