As previously mentioned I discount information and opinions expressed by anyone untill I can determine their biases.
One of the problems with the forum is the difficulty determining the personal information (experience, education, nationality, etc) that is necessary to determine bias and perspective of any individual poster. To find the bias I often have to run specific post by people of known bias (sometimes this is done for us simply by a frequent poster responding to these posts).
On the other hand a wide range of bias and perspectives often leads to new channels of thought.
