I just looked up the topics for cascadiajs and it looks awesome! I was disappointed to find out that all the tickets are sold out even though it's a virtual conference. I know you are just a speaker, but do you have any insight into why there's a hard cap on attendees? Is it simply to avoid potential infrastructure problems that could occur from delivering live video content to an unforseen number of attendees?
