I don't mind the website all that much, although I had to copy and paste all the band information into my own spreadsheet system one by one, where in previous years I could extract it all at once.
On a related note, the worst website in the world was for the Lowlands festival in the Netherlands. For many years it was completely incomprehensible. It was so bad that a group of fans decided to create their own website for the festival where they 'deciphered' the content from the official website and presented it in readable format on their own site.
They developed into a large community that had actually more information and activity than the official site. Incredibly, this situation lasted for 6 years
