I'm on acronym overload, I'll bet you are too.
So be warned... this post is filled with geek speak.
I just learned about Sloodle.com, a hybrid virtual gaming environment built on a Moodle platform. They've got a YouTube video up that demonstrates how to blog through to Moodle from your Second life Avitar.
This stuff is out there. Take a look if you're curious: http://www.sloodle.com/
This is Turbo Dweeb City, but a fun example of what folks are creating in virtual environments like Second Life.
Does anyone out there have a Second Life account? I signed up when ISTE established a presence, but Im just stumbling around at the moment.
