Primarily these threads are set aside as a constructive space for tangential discussions which are off-topic on other threads, but which may still be of much interest to a subset of commentors. This is a space where those 101-level questions that are discouraged on our non-101 posts may be asked and answered. This is a space where highly contentious discussions can be diverted to minimise splash damage elsewhere. Every now and then a passing vexatious contrarian might be quarantined here briefly before passing the plonk-threshold. For an Outline/Guidelines for how #spillover works, see Spillover #1
