A Blog Around The Clock 
Among major bloggers at ScienceBlogs, I’ve lost some respect for Laden over this; he has come off to me as a pretty uncritical “fluffer” of this issue, to the point of getting huffy when I asked him if he had motive while pointing out that NASA had clear motive – budgetary/fiscal – for its actions.
Which is why his posts are not included here…

To clarify – I just did not have time and energy to read through Greg’s post. I did not include posts I did not read. I have to be somewhat selective lest this collection gets too long and unwieldy so I include only posts I have read AND I think add to the discussion. Perhaps he makes good points, I don’t know, and have no time, energy and nerves to go back now and slog through again.
Bora, thanks for the clarification.
I wrote two posts on this. One does not critique the research at all, and that was not the intent of the post. Rather, I used the possibility of A/P substitution as a foil to discuss a totally different issue related to Darwin and evolution. So, while I would have thought it would be included here since it is related (and the NYT saw fit to point to in, and so on), I can see that a reasonably narrow definition of what constitutes membership on this link list would exclude it. And it was long.
The other post specifically address the question of critique of NASA. There has been a lot of critique of NASA’s handling of this and much of that I’m sure is valid. However, the initial critique by many bloggers consisted of an uncritical mixing of concern over claims by various press outlets of aliens or life forms unrelated to anything else, and so on, accusing NASA of sparking these claims. As far as I know, none of those claims was made by NASA or implied in their very short initial announcement, though I can see where someone looking for aliens would see aliens. In other words, I felt the critique should have been focused on the news outlets that were hyping the story from, essentially, nothing. So that post is not about A/P substitution, but rather, about the hype. Interestingly, my post calls for a discussion of the issue and how NASA could have done better, and of all the comments about conspiracies and the validity of the research, there were exactly two that hit the mark, and both did very well.
And no, Socratic Gadfly, while it is a little bit interesting that my redirecting ‘blame’ towards Gawker.com and such led you to think I was somehow involved in a conspiracy, it just isn’t true. Oh, and I did not say NASA lacked budgetary motive. In fact, I said they did. I noted that research institutions have it in their own interest to have positive and widespread press about their work.
What is “Conspiracy Theory” is what the Domain of Ignorance rule Our Minds and Psyche-And The Arsenic Bacteria Press Event of NASA manifests plenty of ignorance to go around and admission of Ignorance is not synonym to admission of guilt either – Often We do not know the magnitude of many discovery as we comment on and I for one admit that lacking right away and secondly rarely we know the exacting environment the research is conducted at NASA and those who are there ,are there as Stakeholders of the Institution they work for.So They would seek recognition and support from the public-very normal and natural human response to outer environment i;e.”The Public”. So, the Press of NASA is quite O.K. on that ground.On the basis of scientific grounding of the research outcome I am not at all full of possessions of technical details or know-how-so I defer to the ongoing debate as reader only.Muhmammad Zamiluddin Khan’92,HSPH,a. k. a.
