I think it was meant merely as an observation, but I took it as a compliment. The guy who writes the spec I'm working from said that I look at the website "from a user's viewpoint". I'm really pleased he said that, as I have been working on that recently.
Update: Hugh's got some thoughts on the matter.
@media print CSS thing to hide the navigation, search box, banner ads etc. so the printed version is much cleaner. Just how the printer-friendly version would look, in fact, but much quicker to write.
I guess I spend a fair bit of time being annoyed by hard-to-use websites, or even just little things on generally good websites, so I try to spot things that would annoy me if I was the user.
