Vinly for DJs definitely Dying...
...in my neck of the woods. Which is Austria/VIenna. Truth be told, I bought my last new recorded 12 Inch in 2009 so.... Anyways, recently I got the vinyl itch again and checked some of the small dj specialist outlets that I used to buy from for roughly a decade, if not 15 years. There were 5 such stores back then, today it's only 2 which are still in business. The rest closed shop for good.
In the big electronic stores I occasionally visit due to demands regarding my job (buying computer gear and such) I definitely see a resurgence of vinyl, strangely enough. The biggest chain store here kept a small bin of vinyl over the years, but the last two years those are expanding! And it's all the 180g stuff! Albums!
So yeah, there is a small vinyl renaissance, but it's not DJ vinyls. All in all, I like vinyl to stay, so I am not opposed to the otherwise rather questionable 180g vinyl cult of late. Because it's to a great extend a little bit of a snob-thing, isn't it? But personally I don't care for the actual product, I am in my mid30s now and started buying vinyl 20 years ago, and it was almsot exclusively dance 12s. Never bothered to buy albums on vinyl, just CDs.
Yet, I can't do the mp3 DJ thing. I have tons of mp3s of course, but I got no attechment to it emotionally, whereas I still love my few 1000s of Techno and Dnb vinyls.
