Mare Nostrum

I like my first life, thanks

Since I've been doing some research on the state of Web 2.0 technology adoption, I spent some time looking at Second Life, There, and other virtual world applications. I've reached one preliminary conclusion:

Either I'm really getting old, or these applications are really goofy.

I've heard people try to position Second Life for business. I know that companies are trying to market their products through these virtual worlds. But are they a collaborative tool, in the same fashion as Wikis, blogs, IM, and the like. Uhhhh, probably not.

If I'm missing something, please tell me.
