IMO online vs in-person isn't the only comparison to make. In 2024, you also have to compare against podcasts & Youtube. Beyond simply starting your own content channels, there's a speaker circuit for interview format podcasts, who have the audience and logistics already nailed down.<p>Using the author's own criteria:<p>1. Coordination. Podcasts solve this by fitting into various niches. Audiences self-select by topic pretty effectively. Expert speakers can easily see various proxies for audience: downloads, ratings, subscriptions, comments, etc, and review past guests and topics for matching suitability. Whereas with this conference you really have no idea about the audience size.<p>2. Distillation. Most podcasts I listen to are an interview between a host and a series of subject matter experts. This format substantially lowers the participation barrier for the expert: hop on a webex and chat for 60 minutes. On YouTube I think there's probably room for an "invited talks" format, like a tight ten - fifteen minutes on a topic, without the usual banter. Arguably HYTRADBOI is a concentrated version of that, but none of the videos are findable anywhere other than it's own site, and hasn't really seen traction on HN. Which brings up to...<p>3. Serendipity. YouTube kinda does this by default, though admittedly watching a KubeCon video is likely to recommend another KubeCon vid that was uploaded at the same time than something from a different tech conf.<p>The author seems to lean heavily on the value of community chat but frankly, annual conference communities are kinda bad at it. Either there's too many people trying to talk to The Expert or not enough and the moderator has to beg for participation. I kinda prefer the discord / slack / IRC 24x7x365 community discussion model, where there's more incentives to help each other out versus the transactional conference window after which you will likely never see these people again.
