AvaCon is another virtual world company that is notable for its work in organizing and hosting real-world conferences in the past. They run an OpenSim grid called AvaCon Grid, and they appear to have hosted a series of real-world Avatar Meetups:
AvaCon hosts and produces a series of educational lectures and community gathering meet-upsthat reach approximately 15 to 40 attendees per event and take place in various regional cities such as Austin, Boston, New York and San Francisco.
These meetups feature a single panel discussion, presentation, artistic or musical performance, or community event to foster knowledge sharing and social networking among attendees who are interested in broad technical, scholarly, scientific and creative uses of virtual worlds, augmented reality, and 3D immersive and virtual spaces.
These meetings appear to have stopped in 2014, however. Their news page hasn’t been updated since October 2017, and I notice a lot of somewhat dated content on their blog, which leads me to believe that AvaCon is not nearly as active at the moment.
I was surprised to discover that AvaCon produced the Second Life Community Conventions of 2010 and 2011. (There hasn’t been an SL Convention since then. I guess people just lost interest, or maybe the organizers got burned out. Organizing a convention is a lot of hard work!)
More recently, AvaCon was a co-host of the 2017 OpenSimulator Community Conference, so it would appear that they are still at least somewhat active in OpenSim projects.
