The first weekend of 2021 is the best time to summarize the professional successes of 2020 related to sharing information. It was an interesting year related to sharing information and speaking at conferences/meetups.

Almost all conferences were in online mode. It was a new experience for many speakers because you had to give whole presentations to your webcam, and it's an entirely different feeling than speaking at offline events.
