I don't think this is a bad idea. This can be done easily without the need for any involvement or endorsement by P123. With @marco 's permission I think I will just go ahead and implement a sentiment survey this month for the month of May. If there is continued interest (and something more popular is not implemented before then), I will let (request that) someone else take over next month (for June) with any desirable changes.

I would be happy to make any suggested changes or suggested changes could be made next month (with someone else posting the survey). Certainly P123 could direct this or facilitate it, I would think. Maybe make it a new forum category. Or decide it is not a good idea or should be done a different way.
Whether I end up using this or not myself will depend little on the discussion above but rather on the out-of-sample results if this is continued long enough to get meaningful data—which seems possible and potentially useful (depending on the results).
