My comment on this article in Relevant by the author of Hipster Christianity:
2000s - hipster
1990s - alternative
1980s - yuppie
1970s - disco dancer
1960s - bohemian / hippie
Maybe there are two classes of hipsters - those who genuinely like the latest stuff (clothes, technology, new ways of approaching things, etc.) and those who pursue those things for the acceptance/admiration of others. I think a lot of this ties in with personality types - someone with an intuiting preference is naturally going to gravitate toward what's new and what's futuristic, and if they also prefer perceiving, they will definitely not go with convention.
The bottom line is if you're being true to how God made you and to his Word. Individuals should be eclectic, and therefore churches, too. We don't need to try to be different - we naturally will be if we're living the way we were made (with our unique giftings and interests) and following Jesus. There's a lot of talk about authenticity, but that can be faked too - ironic the things we'll do for popularity...which is why we always need to be checking our motives, and spending time with God, so he can strip away those insecurities as we get grounded in his love, grace, and truth.
Despite the great insights that I'm sure are in this book, one thing I'm concerned about is that it will prompt people to judge/define others based on superficial stuff (appearance, speech, etc.) without getting to know them first. Hopefully the author warns against that. I always appreciate context, so it may be that this article would sit better with me if I were reading the whole book (which I hope to do eventually).
