i have to agree with some of the above ^^^
some scattered maybe incoherent thoughts

:
to me, Hipsters don't seem to care whether they are seen or photographed ever..not so concerned with final effects, esp of clothing/physical beauty etc. more about ideas/passions/arts/obsessions... many would actually be mortified or at least amused to be plastered all over some fashion forum.
OTOH, many Scenesters seem to absolutely *live* for clubs, parties, certain neighborhoods where they might becomethe next It girl or boy, or fall in with the 'right' crowd. very much into designer looks, but giving an affluent-yet-slumming - 'high-low' or expensive artsy look.
hwvr for the young Sceneys there's the UO, american rag/salvation army contingent which overlaps some of the Hipster aesthetic. i think Hipsters dress more modestly/covered-up than Scensters(too many visible hipbones). In general, both groups are thin(compared to the majority) but Scenesters seem thinner, often to a cracky/scary degree. I've met & seen Hipsters from tiny to obese.

Unlike Scenesters, who appear to always travel in packs, many Hipsters are loners or have a tight-knit circle of friends...don't seem to care about being at the 'just about to happen' club or whatever. may be rich or any other class but not too concerned with seeming wealthy. most i've don't give a rat's about designer. hipsters do thrift and vintage too of course but i think they're pleasing themselves... not readying for their 15 minutes or to become tight with some trust fund kid.
i'm sure there's overlap with Fashionista Hipsters and maybe some Scenesters w/Reclusive Tendencies but most Scenesters almost cease to exist without adequate audience to marvel at their branche'/faux weird/often drug-fueled eccentricities.

a Hipster is fine at the no-name bars/cafes/diners alone or with friends. in their groups i've seen less antics and 'look-at me' gestures and public prancing/staggering/posing than the Scenie groups.
many Hipsters seem perfectly happy pursuing their projects often in obscurity. Scenesters sometime clown/stunt/try anything to be noticed and admired. Many also worship the luck of physical beauty(yes, we all do.. to different extents.. yes but for Scenies it gets cultic quickly) while Hipsters act more cool about someone being attractive.
not to pick at anyone but Hipsters seem a bit more stable and intelligent(okay maybe a bit dry) and Scenies seem quite flighty and uh..less intelligent(okay maybe fun in small doses)?
uh... date/sleep with a Scenester but marry a Hipster?
