I think what you published was actually very reasonable.
But, what about this? what if you were to create a awesome title? I mean, I don't want to tell you how to run your website, but what if you added a post title that makes people want more? I mean Gästebuch is kinda plain. You could glance at Yahoo's home page and watch how they create news titles to get people to open the links.
You might try adding a video or a related picture or two to grab readers interested about what you've written. Just my opinion, it might make your posts a little bit more interesting.
