The flagging annoys me... the infamous "experiment" was OK, hoping that it was no more than a temporary experiment. The ongoing stuff... especially the infantile "border skirmishes" between people having petty disagreements? That stuff reeks of the less charming reasons why sites like Reddit (and Digg, before) turn into strange clique-ish snakepits.
But... we have to move forward, and if the right people create good content, it may be able to overshadow the nonsense and eventually drown it completely.
