You might already have noticed it: I added some advertisements to this site. Since now I am paying a hosting provider to host this site, I thought that I might try to get back at least some of the money I spend for it. The advertisements are related to the contents of the page, so I only added them the pages of the individual items. This makes the chance bigger that they may actually be useful for my visitors as well. I decided to give it a try for about two months; if I notice at that moment that they are not working, I will remove them.
People using a modern browser won’t see the advertisements, since the advertisement script does not work when the page is processed ad XML.
