Ain't that the truth.
My sense is that the number of threads engaging with the substance of the playtest packs has diminished with each new release, and that's particularly surprising given the amount of material in the April packet. Quick judgements replace thoughtful engagement with actual play experience, and there has been remarkably little substantive engagement with Playtest 5.
Part of that is fatigue from the process, but I also believe that the community feels that the changes are mostly on track. That's way I was so disappointed with the revelation that the designers are likely backpedalling on ideas that do not instantly get overwhelming support. That release, if nothing else, will increase a feeling of disengagement (and, unfortunately, will reward snap judgements).
