While we are debating the 'minutiae' associated with the AF447 accident, I have been doing some work on a Search Engine that will selectively search the individual PPRuNe Rumour and News / Tech Log threads on the subject.
At the time of this post, there have been 13 substantive threads on the AF447 event, involving 25,184 posts. That doesn't include those posts deleted by the moderators, e.g. 949 were deleted form the first thread - Air France A330-200 Missing.
The BEA's Final Report will no doubt attract many many more posts!
