Hey everyone!  I'm a bitcoin newbie (obviously) and just signed up for the forum.  I'm a software developer (primarily Java).  I don't yet have any BTC to my name, but have been doing some pooled mining with DiabloMiner and am up to about 0.6 BTC (payout at 1.0).  :-)  I'd like to better understand the underpinnings of bitcoin, so here I am.
