Some of the writing is funny, some is distracting from its purpose. The Dubstep entry for instance spends most of its time bashing brostep and skrillex which is a shame as it glosses over the first few years of interesting music before it devolved.
It never devolved; the mainstream split off from the genre, which remains underground and still has a couple dozen labels actively producing music, as it has for the last decade.
The genre is actually evolving constantly and there's a fair amount of interesting material and new artists. But it's back to being a niche much like jungle is nowadays.
Yeah, but Skrillex! He's bashing the music, saying it's garbage isn't exactly controversial, it's ripe for skewering. And it's supposed to be his opinion; if you like Skrillex the site might not be for you
