>>2 Not really, there are quite a few vapor 'artists' still releasing stuff - take bl00dwave, vincentRemember, 猫 シ Corp., 静脈 v e n o, or SODA lite for example, they've all released some material (at least one song for sure) over the last couple of months
Though, the offshoot of vaporwave that is future funk is still alive and kicking. I'm something of a future funk fiend, I'm just a sucker for good funk/disco samples.
