Can't see the article but I imagine a big part of it is a combo of clubs continually being booted to new locations in cities to the point you kind of have to get tickets in advance for one place or run the risk of going there, being turned away and having absolutely nothing else to do in the area. To battle this there's loads of venues that seem to almost exclusively do shows that end near midnight and I've never been to one that wasn't completely devoid of atmosphere (hard to enjoy the music when the people next to you are talking at length about some work deadline they have).
