I think what you said made a lot of sense. However, what about this?
suppose you were to write a awesome headline? I mean, I don't want to tell you how to run your blog, but what if you added a headline to possibly get a person's attention? I mean Gästebuch is kinda plain. You could peek at Yahoo's front page and watch how they create article headlines to get people to click.
You might add a video or a related pic or two to get people excited about everything've got to say. Just my opinion, it might bring your posts a little livelier.
