I have decided to adopt the following Code of Ethics (taken from Desirable Roasted Coffee via Scoble):

To write, publish, and be read is a privilege and responsibility. Being mindful of that privilege and responsibility:

# I shall not barter my words or my silence.
# I shall write and advocate openly and honestly.
# I shall strive for accuracy, avoiding errors and correcting them immediately when discovered.
# I shall strive for balance; even in advocacy, I shall not distort or suppress obviously relevant facts to bolster my argument.
# I shall welcome and invite rebuttal, debate and discussion through comments, email, and trackbacks.
# I shall disclose my sources fully, through credits, links and trackbacks, unless the source, with good grounds, has requested anonymity; moreover, I shall trackback where relevant and possible.
# I shall respect copyright; my own words will be licensed with a Creative Commons license.
# I shall let the record stand; I shall not delete posts, or parts of them, unless not doing so would violate one of the foregoing principles, and shall give notice that I have done so. If I modify a post, it shall be by adding to it; and I shall mark these additions clearly.
# I shall reveal material conflicts-of-interest.
# I shall, as a citizen of Australia, remain mindful of my duty to truth, the citizens of the world, and the laws of Australia.

I have modified #10 from it’s original as it was not particularly relevent. I believe my variant to be in the same spirit however.
(Original text reads: 10. I shall, as a member of IABC, a trained reporter, a resident of the European Union, and a citizen of the United States of America, remain mindful of the IABC Code of Ethics, the Code of Ethics of the Society of Professional Journalists, and the laws of the European Union and the United States.)
