This is kind of outrageous. I sort of look at ajaxian as a reliable and interesting source of info on webdev, but now I'm totally turned off. I'll make it a point to not visit. Shame on them.
First off, this is bad behavior on Ajaxian's part, and they should learn that people will appreciate them just as much (more, actually) if they send the user off-site to the content they're pointing at.<p>Second, shouldn't it be possible for Roman to prevent another site from embedding his IFRAME? Either catching the window.parent.location in JavaScript or only serving the IFRAME page if his own domain is in the referrer?
Here's how their post starts:<p><i>Román Cortés is having a lot of fun with CSS tricks these days. He just built an example rolling CSS coke can that uses background-attachment, background-position, and a few other tricks to get the effect. No fancy CSS3 needed here!</i><p>It looks like they gave him full credit for this. Unless he was selling access to this blog post, I'm not sure why this is an issue. It seems even more benign than piracy. (And as sophacles points out, this uses less bandwidth than a direct link, too.)<p>Clearly, Román is willing to have his bandwidth used in order for people to look at his cool CSS trick. So why is this a problem when it's a little less bandwidth, plus a third-party endorsement?
Doesn't a direct link cost more bandwidth? In which case does the one google ad on your site make the difference in cost/income? Further, does the ajaxian style hotlinking -- full credit and source link provided, constitute the same think most people think of for hotlinking (no credit, just images from someone else's site...).
