Second Life/Web 3.0

So, we had our meeting in Second Life last night.  The meeting was an introduction to the navigation of the program, and an overview of the basics.  This was actually my third time in the program, but the first time that it actually made any sense.  This tool wouldn't be a recommendation from me to anyone without an initial guide to help you along the way.  I realize it's something new and I have to learn, but my frustration from the first two times made me want to throw in the towel.  Last night I was able to maneuver around a little more comfortably, and even played around a little with appearance. 
SL gave me an overall feeling of meeting in Skype or similar, just with Avatars taking the screen rather than voice.  I can see this being used as an educational tool and as a "game" as some might say.  Meeting in Second Life might bring a little more interest for educators versus just a normal conference call.  For a professional meeting, this may not be the best tool for staying on task, as people may tend to want to "play" and do other things featured on the program.  The notecard app was cool, I didn't know you were able to share files, and it was easy to just click on the person you were sending it to. 
I'll go in SL over the next few days to explore things I weren't able to last night.  I want to see what else is out there, maybe join a group...go shopping!
I think SL meets and exceeds our definition of a Web 2.0 tool.  It is a part of the second generation web, but it is more of what the norm for Web 3.0 will be.  It encourages collaboration on all levels, and a person is able to show personal expression in every aspect.
I really think that Web 3D is already here...just needs some clarification on what it really is and how different it is from Web 2.0.  SL is a program that brings web 3.0 to every home, making it easier for people to know what it's all about.  I would say in 1 decade, avatars and 3D will be the norm for communicating over the internet.  It will become more advanced, like speech and movement recognition.  Again, these avatars are giving people an opportunity to be something they can't be in real life.  In the virtual world you can have anything you want, there aren't many boundaries, and you can go places you've never been before.
Web 3.0 would connect to these theories in a way because with the avatars, you are the "surrogate".  You would control the avatar, and it would be a reflection of you.  But the avatar couldn't experience human feelings, emotions, the mind etc.  Although the virtual world would be all idealistic thinking, we need to realize that we are here in the real world.  Virtual worlds do not deal with anything that isn't ideal, like death.  Although we are moving into more technological society, we can't expect for our real world to just end.  We will always need to remember that the virtual world is not the real world, and we can't expect it to be.
