There is the saying "All the good things come at once". It appears this also applies to the adult webmaster scene. Even though it might not be beneficiary to everyone.
There are at least three different webmaster events happening more or less at the same time. That indeed will keep some people really busy flying around and it might not be of any benefit to the organizers. There is no doubt that they will see less visitors at each venue this time as many professionals will not and cannot attend each event. Maybe it's worth to talk to each other next year before setting the dates...
Budapest, Amsterdam and London. Three cities to visit between the 20th and the 27th of September. And not to forget Kiev and Las Vegas, however at least those shows are not focused on Webmasters. Pheeew.
