Past Discussed Quarterly now has a web site at edublogs.org. To give credit where credit is due, this is mainly the work of Alun Salt. In addition to a description of the publication, there is an announcement of volume 1. The comments to that page show that some posts have already been submitted by their authors. The page How to Submit an Article gives further detail on the publication process.
Speaking for all of who are interested in moving PDQ forward, it should be clear that this is an idea still in formation. The back-and-forth to date has been interesting and we welcome further comments either on this blog or at PDQWeb.
