Years ago (I just say Worlds Chat 1994) I was totally excited about virtual worlds. Now, when they start to be really good, I just do not find it appealing to waste time inside them. I guess I am already too anchored in the real world. Anyway, Trusted Reviews published an interesting review of Second Life. The reviewer also tried out virtual kissing and more (see photo).

Quote from the review:
"I almost feel odd in saying that I've really enjoyed my experiences in Second Life. I've had some interesting conversations, and had a good time fiddling with object creation and clothing. At this stage, I haven't really delved into the coding aspect of Second Life, but I will definitely have to give that a go at a later stage. "
Read the full review. Via digg.

There are 1.7 million residents in Second Life.
If you want to catch up on Second Life and what it is all about there is the book Second Life: The Official Guide.
