Even with my first personal blog, meeting bloggers all over the world, reading (and listening to) what they have to say about topics, ideas, news, rants, etc. is what makes it fun!
Meeting people thru blogs changes the way you look at the world. It gives you that boost to go on with your plans, to try even if you are not confident enough, or to help others with some problems they meet. The possibilities are endless and varied, actually, when you have some form of a network to turn or refer to.
