...currently trying to give a little back to SO after using it extensively to get started with Android and other Java programming (and marvelling at the ability of SE sites to aid human progress and organize knowledge). (I made a few posts a year ago, but really just got started.)
At the moment:
on SO (and SU a bit) this means answering what few questions I can.
on Meta-SO this means using my fresh perspective to provide feedback on what about the site can violate new users' expectations and confuse them (AKA being a whiny n00b).
