I love it when a thread comes together. Just wanted to share my respect for a perfectly crafted question and answer.
The Thimerosal post could be considered an example of agendafilter, yet the resulting thread is a thing of beauty. Reasonable and enlightened discourse at its sunshiny best. See? We CAN have nice things!
What constitutes a good post? Although there is no simple answer, perhaps we can get a general idea. Respond with a link to a post or thread that you think is good, and (briefly) explain why you think it is good. This thread can then serve as a database of good posts (and without needing any new code!) for future reference.
