VWBPE 2013

I've been to a few Virtual Worlds Best Practices in Education (VWBPE) conferences in the past, and have even presented at one in Second Life.  However, this year VWBPE is planning on holding its conference on four different platforms, which I find fascinating.  These platforms include

• Second Life
• Cloud Party
• Jibe/Unity
• Jokaydia

The only one I've used out of the four is Second Life, but I would definitely be interested in trying the other three.  Has anyone ever tried these platforms before?

Also, for a more comprehensive write up on the upcoming VWBPE conference, visit Daniel's  Voyager blog.  The conference is free and I'd highly recommend anyone interested in virtual worlds to attend.
