What is considered the most appropriate way of reporting about progress towards an answer to my own question(s)?
The options related to MO I see, are either in form of an edit, in form of an answer or, by creating a new question in the vein of "is that already known".
The other option, outside of MO, would be to submit something to e.g., arxiv.
The topic is rather exotic (generalizing the notion of planar convex hulls to symmetric TSP instances in various ways) and the progress-report might be a bit lengthy; therefore I would appreciate some opinions on what to do best.
