From watching the video, I learned that nothing that you post is private. Anyone and everyone can see it. So post something nice, and not innapropriate. I look at a lot of my class mates blogs and saw some of them using fun and creative ideas. I think I am still getting used to posterous, so I am just learning how to customize my blog. I like a lot of my classmates ideas, and will probably get some ideas for my own blog.
