No, I have not yet participated in such a forecaster community. I would be interested in analyzing sports events, publishing forecasts, reading other people's forecasts, participating in forecaster ratings, working on mistakes, improving my forecasts. I think this is a very promising topic. If you do this regularly, you can greatly improve the results of your forecasts. Of course, these should be detailed analytical reports; this is the format that, in my opinion, will allow you to improve most quickly. It is very important to understand what characteristics you need to pay attention to in order to make correct forecasts. By the way, if the number of such forecasts is very large, then it is logical to involve artificial intelligence for data processing. This will allow you to create truly useful analytics. And in the future, as the skill of predicting the outcome of sports events grows, you can already make money on this analytics by making real bets on sports events.
It's great that you're interested in the topic of forecasts. Tell me, do you have a preferred sport that you could give forecasts for?
