That's funny, it looks fine in my Firefox 0.8... all except the horizontal menu at the top, which is broken into two lines (I don't think that's intended, is it?) and has a line-height of way too little, so when hovered over, the background covers half of the link above/below the active one...
And why would you need good Dutch to read a Danish blog? ;)
I would, however, suggest adding a bit of padding to the right side of the menu. The dotted underline under the red links goes all the way up to the border and gives the impression that there's more (ie. vertical scrolling), which there isn't—and perhaps making that part of the menu a tad bigger, it's very small.
Other than that, it seems to work as you want it to—I can't say it's a design I would choose for myself (talking about 'overpyntet' here, the one it loaded with; I haven't checked any of the others), but it's your site, not mine, and the design is well done.
As for the content, there are probably a lot of people who find it useful, but I guess most people here will already know most of it (target groups, etc.). What I mean is, the content is good and useful for the target group you're going for, which seems to be average internet and computer users, not geeks like people here :P
And it's so nice to see a Dane who can actually spell! That is a rare thing—although I did spot a 'ganske vidst' in there somewhere ;)
