Just to clarify - the review process at JoPP is _not_ that everything that is submitted will be published irregardless of quality.
The peer review process page (http://peerproduction.net/peer-review/process/) states:
"1. PAPER PROPOSAL
1.1. Non-special issues
Authors use the contact form to send a proposal to the editorial team who will assess the suitability of the proposal for the journal.
1.2. Special issues
Authors submit proposals directly to the special issue editors."
So there is an upstream selection by editors (as demonstrated on this list when somebody said they were knocked back).
Once the publication process is launched then yes, normally everything (initial sub, reviews, responses, final paper) is published.
