One further comment from a heavy database user for what it's worth:
If we had a list of 'tags' that anons could enter as they post (in a specific format, e.g. preceded by **) covering topics that emerge (such as 'mkultra', 'bridge' etc. - related to topics brought up by Q) when searching through the data it would serve as a way to link crumbs by subject and as an additional variable / filter in any search would serve to streamline any search.
these would have to be moderated by BV / BO / Baker; would not be any more work than creating the notable posts per bread, although would be useful to find a way to insert them after the post identifier to create the link (i.e. >>xxxxxx within/2 **xxxxxx = TRUE).
Historical would be an issue but if there were some way of batch-adding at data assimilation stage based on linked crumbs, as well as specific 'meta-moderators' as we run searches etc.
However it might work - principle is an easily assignable value to identify crumb subject based on Q's topics so more information can be retrieved via regular search.
