most of them won't be around when the next trend comes along. There are a fuck load of young writers these days compared to what there was 10 years ago, but the percentage of those who are consistently active is on a massive decline, I guess its like everything in life, when cunts have everything at their fingertips they take it for granted.
As for style, now that it's basically acceptable to directly bite, and even in some cases (Cekios) it's praised provided you know your way around a can, a lot of writers are skipping the whole progression phase and just picking out a style they like, in most cases whatever is popular at the time, and running with it.
