Safe Blogging...what is safe?

Some people use blogging as an equivalent to a diary or journal while others use it as a resource. Blogging sites in my opinon aren't any different than sites such as facebook or myspace. We can post so much on these sites such as pictures, thoughts, comments and ideas. They also have privacy options that the user decides whether or not they would like to use in order for people to have access to their page/personal information or not. On any site I don't think that it is wise to put any information about yourself that you don't want people to misuse.
