I have an online journal myself. I think if you are intelligent and enjoy writing, then why not. Leo, I definitely think you have that quality.
You know what I can't stand about online journals? People who talk like they're from the ghetto. Umm...lemme think. They stay stuff like waz up wit dat and other stuff in their entries. It's hella annoying! I cannot stand it. I may talk like that sometimes, but I sure won't write like that.
