If I had a hammer

Do you know how this song goes? "If I had a hammer, I 'd hammer in the morning, I'd hammer in the evening, all over this land. ... I'd hammer out danger, ...warning...I ....hammer out the love between my brothers and my sisters all over this land...um um um um." Well, I am gathering that this blogging is a way to do so. How do I really get started? I need to learn how to use these technology tools. I am fumbling to figure things out, but I know that is a strategy. I would just like to become more efficient. Any suggestions out there?
