I make all my papers available through preprint servers when they are ready, and no longer see any reason to send them to journals, even open access ones. My current research interest is in meta-science, specifically ways to identify errors and fraud in the published literature with or without access to the underlying data.
Bill Simmons and Kevin Wildes are known for a podcast in which they pitch half-baked ideas. Some ideas are good, some not so much. Similar to this podcast, in addition to discussing my complete manuscripts I will pitch ideas or provide initial steps in analyses that could be completed by someone with more experience and interest in the field.
