That's a big question. Here is an article to start with. I am sure everyone can add a little something and make this the worlds LONGEST thread.

Stick around and look around, Check out other's blogs....it's really hard to know everything at first , but as a group, they really stay on top of it here. I still find myself answering basic questions that I should have known by now.
Best advice I can give is Blog something that you know and love...then it doesn't feel like work, and you never run out of ideas. If you blog
just for money, you won't make any, until you have passed the learning curve.
Good luck!
