Wow, love the idea of a VC. The big thing as you mentioned is the audience, people comfortable learning and attending in a virtual environment; I know many who wouldn't be. I see all the upsides you mentioned. Another one that I think could be key from an org standpoint, speakers. You mentioned the travel costs of attendees, the logistics of a space. Well a VC you don't have that budget - so maybe you can bring in more, better, bigger name speakers? Just skipping the expense of the business class flight and hotel room, maybe opens up the budget for those speaking fees. On the cons.. the technical stuff is big; if you're gonna DIY I'd expect an army of techies to be on standby for all the what ifs, many many dry runs to make sure all is up and running. And for meal breaks and the after hours networking (which yes is totally one of the best parts of a conference) ... why can't that be virtual? You could build time into the program, book a 'brown bag lunch' or evening mixer where everyone chats and swaps LinkedIn cards? I could easily enjoy a presentation while sipping a glass of wine, hopefully not spill any on my keyboard. :) FWIW.
