I've taken the Straw pledge, have you...?

James Graham has set up a pledge to write to Jack Straw to tell him to not be such an idiot in attaching TheyWorkForYou.com.
Straw's premise is that recording the number of MPs Written Questions to ministers is encouraging MPs to submit more questions to appear higher in the stats recorded by TheyWorkForYou.
The website has already bowed to some of this pressure unfortunately: they no longer give an absolute ranking of the MPs quantity. But they have maintained the record of the number of 3 word alliterative phrases used.
Straw's outburst prompts one to wonder why government and other agencies publish "performance" data. Has newLabour decided that it doesn't like performance measures when these measures aren't in their control?
