Don't kill the messenger. I'm sorry that that's how I feel, but as the consumer I'm just saying that I don't like the product (online conferences). Sorry that this is demoralising, but I'm not gonna start liking a shitty product all of a sudden to make someone feel better about it.
I'm sure there are other people who feel differently, I have not met them yet, which makes me believe that the group of folks who find an online conference okay is significantly smaller than those who hate them but don't let yourself getting stopped by my personal opinion, if it gives you joy to run an online conference then be my guest and best of luck!
