it probably depends on what specific btc aspect you are interested in.
if you want to be "just" informed in a timely manner - the forum here is best.
if you want to know stuff before it gets posted here you can listen in on the irc channels suiting your interest.
if you want to be even ahead of that you might fly to japan and try to bribe mk with sweet coffee
but so get at least one answer in the form you were expecting:
