On topic, hipster metal is something that I associate with wolves in the throne room/velvet cocoon/tumult/hydra head records stuff. I.e art school kids playing with the black metal aesthetic "Ooh exiting 'outsider music'!" and so forth. I wouldn't worry about it though, cool hunters like that won't stick since they are always looking for the next thing.
The final statement I'm not so sure about. I believe "hipsterism" is the result of an overactive technologically advancing society paired with the stunted and even regressing growth of human beings on a personal and intellectual level. We have exponentially evolving communication and transportation, as well as an array of devices which enhance nearly all personal comforts, and an overabundance of information flow, with very, very little of these resources being used for anything but gross, self serving ends. One result being a synthesis of everything that has been considered "cool" in the past in an entirely superficial manner, or hipsterism, and I don't think it's going away anytime soon. Things like cameras and recording devices were what set us apart from most entertainers, and in the past you either had to have intelligence, skill, money or popularity (probably mostly the latter two) to get a record out there or make your own film. Now that all of the technology can be purchased for a reasonable price and occasionally even all on the same device there is a severe ambiguity between art, artist, entertainment, entertainer, and the average joe. At one point the artists and entertainers (and political leaders and so on) were more fixed in their status like gods in the pantheon, but now this separation narrative between the little guys and the celebrities is less and less prevalent. I think at first this resulted in the rise of an indie movement, but quickly snowballed into a nebulous haze of myspace music and reality television, promoting average idiots to the level of stars and demoting stars to the level of average idiots. Hipsters often nostalgically idolize stars, writers, movements and artists of the past or of the underground while the mainstream media attempts to catch up to and guide this movement with cheesy throwback movies/music/clothing fashions and horrible adaptations of underground and/or genuine artistic output (to cash in obviously). However, where does this leave us? Nothing new, unique, interesting or relevant is being produced and what is left is slowly made more and more accessible to a mediocre audience and remade by hipsters to appear like its former self but lacking all of the substance. I swear if I hear the band Bone Awl compared to Ildjarn one more time I'm going to fucking vomit.

I stumbled across it awhile ago and have not found a better example of the "black metal hipsters" I've met in my own life. They seem to always find the black metal genre through noise, hardcore punk, and grindcore, and completely confuse everything the music is about for some other, more liberal and generally cheaper ideology. They mock the music and revert to irony when cornered about heated topics such as murder or racism, or even why they like the music in the first place (among other things), make horrible albums which are far closer to noise, punk, and some kind of prog/indie rock than anything else, and don't even bother with any death metal as it is usually far too complex, and not nearly emotionally bound enough for them to assimilate. The reason why I don't imagine them going away anytime soon is because it seems they've just begun cashing in on the niche genre and are obviously not innovating anything themselves. I've been increasingly inspired to write more of my own music and start reviewing both the hipster crap and whatever unique metal music there still is to try and help crush this trend. I'm eager to hear thoughts on this.
EDIT: I'd like to add on the topic of a reversed causal chain something I was talking about recently to a friend. He mentioned to me that Squarepusher had made a prog rock album which made sense to me since the artist obviously has a great grasp on musical structure. However, I was reminded also that I had heard the rapper Little Wayne had made a rock album from another friend, and that he had to use an auto tuner to warp his voice to the music because he couldn't sing. I think this is a perfect example of the reversal of cause and effect in hipster trends. Squarepusher could probably play several different types of music as he's a good musician in general, Little Wayne, who probably has no grasp on music whatsoever, has merely cashed in on an image rather than genuine skill, honesty, or intelligence.
