Like I said, the poster that was talking about the Chalabi/Miller link is anti Bush, so his conclusions must be viewed from that prospective. If you continue reading on the blog, the owner calls the poster a fool.
The interesting part is that Miller was very strong on WMDs being in Iraq. At the time of the Plame affair she wrote about the British WMD specialist who committed suicide due to the falsification of his reports and Miller included the information that he had been under terrible pressure from the anti-war forces to change his estimates. It was concluded that perhaps Miller was feeling some of that same pressure. (Actually, we know that she was)
Yes, that is the interesting part, especially because Miller was one of the last people the WMD specialist (David Kelly) talked to before he died, and it is debated whether his death was a suicide or a homicide, and at the time of his death he was being investigated as a possible source for British reporter Andrew Gilligan, who was covering a story touching on the British investigation of the origin of the same forged Niger documents underlying Wilson's story.
