Blogs , Wikis and Web Class

I am sitting in a class I'm taking at PSU about Blogs , Wikis and the Web.  One of the assignments is to create a blog.  I've read a couple of blogs and was curious about them but now all of a sudden without giving it any thought I have a blog!  Since I already had a Gmail account it was easy to do.  After I post this message I am going to customize and design the blog.  I like to write but will have to decide what I am going to write about in the future.
