When you are blogging, sometime you have nothing to write. You want to inform readers about something you know. You want to educate them as much as you can. So, you spend a lot of time thing about what you are going to write.
WRONG!
People dont really care about what you know. They would like to know you before they will listen to you. Save the speech to some other times and just write what in your mind. Some people agree and some dont. That is Okay.
It is important for you to write something than nothing. If you really nothing to write, post a picture you took from last trip. Oh, this is a picture of Mt. Baker (I thing) I took from the car last Friday. As you can see, I have nothing to write, but I made you read this. So, what are you waiting, write something. Nobody will bite, usually.
