I believe everything typed was very reasonable. But, consider this, suppose you added a little information? I ain't saying your information is not good, but what if you added a title to maybe grab people's attention? I mean Guestbook is kinda vanilla.
You could look at Yahoo's home page and see how they create news titles to get viewers to click. You might add a video or a related picture or two to get readers interested about what you've got to say. In my opinion, it could make your website a little bit more interesting.
