Enjoyed watching and learning. As you are always looking to improve your livestream I have some suggestions, these are intended as constructive (please take them that way). You mentioned a couple of times you were thinking of using a moderator for the chat - I would go one step further and say you would benefit from an assistant/volunteer to (1) manage the chat and (2) take care of the time keeping so that you don't have to worry about alarms going off, just a signal from your assistant to say ‘wrap up in 2 minutes, etc’. Also, I don't think you should be too concerned about the precise length of the timing intervals, it doesn't really matter if you talk a minute longer or a minute less as long as you get a smooth transition from one to the other. Regarding the chat (or multiple chats that you have), firstly it would be a great improvement to have someone filter out the nonsense comments, additionally that person could help draw your attention to questions or comments that you can actually provide a response on. Having a second person to actually ask the question would be even better in my opinion, it would mean you wouldn't have to read out the question yourself which I think would come across a lot better. Making it no longer a monologue and possibly providing a new dimension to your livestream.
