Well he might be aging disgracefully but he still strings out plenty of thoughtful posts on an (almost) daily basis, so wish him happy birthday, although by the time (and timezone) most of you read this in, it will be past.
I call him NZ's best blogger not because of humility (bugger that), but simply because it is the ONLY NZ blog I read almost every day. It almost never annoys me, it regularly inspires me and is not filled with the tribalism seen in too many other places. He attacks the poseurs and pseuds on the right as much as the obvious targets on the left. He laughs and expresses dismay when advocates of Islam and Christianity are found wanting, but also points out when some on the left actually get it right (though almost always for the wrong reasons).
It's beyond the middle muddle ground of current history that is Kiwiblog, the abusive hypocrisy of Idiot Savant and the "politics for kids" partisanship of The Standard. Not PC has been more philosophical than most, with smatterings of art and lifestyle.
All in all it is a pretty good read, not just because I usually agree with him, but because it tends not to be a rant.
So go over there, wish him a belated happy birthday, he's the best daily read you can get on NZ public affairs.
