Second life

Well, I created a Second life account: I'm KathyLynn Heliosense. I created my avatar and poked around a bit, and I guess I don't get it. Um, how am I supposed to find things? Walking around got boring after a while, and flying was faster but still seemed pointless. I've heard about an information island, but didn't know how to even start looking for it. I have seen an archived author interview on Second life, which was interesting. I guess it's great if you know the layout of where things are and can find interesting places quickly. Otherwise, it seems like a time-eater. Why would I spend time there? I didn't figure that out.
