The blog has been unreachable during most of the weekend (from Saturday 3, around 07:30 PM till Monday 5, 09:00 AM, CET). I'm sorry about that, and thanks to those who reported the problem. After doing some detective work, it turned out that an "offending" trackback somehow messed it all up, so that the weblog could not be accessed. I'm not exactly sure why this happened, but everything seems to work fine now. I regret the fact that many of you found just a blank page, and that I could only find and fix the problem this morning. Thanks for your understanding. BTW, this "black out" did not affect those who read the blog through an RSS aggregator like Bloglines.
