Checking out blogging

Alright, here it goes. I am jumping right into the blogging pool. I need to educate myself about blogging for my work. So I figured why not just start my own personal blog and see what happens. I am not entirely sure if there is blogging etiquette or things that may be inappropriate to blog about so I need my friends help. I am linking this to my Facebook page in the hopes I get the help I need. I am pretty willing to discuss anything (within reason) since this is a public forum. So do I have any suggestions on a good starting point? I think this can be fun, so help me out.
