I'm wondering how's the current state of the art in web conferencing. I don't mean Skype-style conferencing (i.e. with people you already know), but something more like a trade show, where expositors can showcase their products and you can randomly meet other visitors. Around the year 2010 there was interest in this field, but it's been decreasing since then. I found VenueGen (https://en.wikipedia.org/wiki/VenueGen) but it seems abandoned. Do you have any idea why this software failed?<p>I would expect that something like VenueGen, browser-based and multiplatform will have a lot of success in the current times.
