What’s Blog!?

I've been using SNS-kind of things(such as mixi, Face book, My space and so on.) for years,but I didn't use blog somehow.

Using a social networking system gradually made me think that there may be more possibilities to communicate with people over the world if I'm out of those systems.

I mean,I thought Mixi(the social networking system I've been using for two years) is to me a bit exclusive means for possibilities of using the internet.

That's how I was kicked out into this new world of Blog.

So,,,,,What is Blog!?
