I believe everything posted was actually very reasonable.
However, consider this, suppose you were to create a awesome headline?
I am not suggesting your content isn't solid.,
but what if you added a title that grabbed people's attention? I mean Gastenboek inschrijving is kinda plain. You could peek at Yahoo's front page and see how they create article headlines to grab
people to click. You might try adding a video or a pic or two to grab people excited about what you've got to say.
Just my opinion, it could bring your website a little bit more interesting.
