The perceived audience for wobble is quite interesting - depending on who you ask, it's either hipsters or chavs or students or moshers or americans or indie kids... it's kind of a role-call of subcultural bogeymen.
Simon Reynolds describes wobble as the properly hardcore component of dubstep - something Andy alluded to upthread, I think - which is fair enough: it's got the who gives-a-shit attitude to good taste, the dancefloor-centricness, the OTT caner thing. Although it doesn't have the haphazardly yoked together combination of elements and factions that made ardkore 92 so fertile - so it's more like happy hardcore or gabber or clownstep or whatever. Only much more mainstream at the moment.
It's kind of a shame that it's stuck as the thing that took over a previously amazing scene, really - I think if wobble had grown out of some weird metal subgenre people would have less of a reflexive hate for it...
