I agree that dupes can be annoying, but even after being on HN for a fairly long time (almost 2 years) and visiting a little too often, this is the first time I have seen this piece of writing and I found it very worthwhile. For some odd reason, I had never really read fully about Overcoming Bias or the new Less Wrong blog and wiki with all that it has to offer and I think I will spend a lot of time reading that in the next few weeks.

Thus, thank you for the dupe.
