It is something I always wondered about since conferences were a big part of my job and helped in maintaining the right audience. Since the pandemic, I have not attended any because it has been free and in a way, my perception had lowered of the same event nor did I feel the networking opportunity would be good. This could be an option if there is more to really distinguish the paid offering
