Ah. I think I see a disparity in our perceptions.
Your spreadsheet is not a topic or category in Discourse. It is a Google sheet shared in Google Drive. Its purpose and function are very different from the purpose and function of topics, which is discussion. I think its relation to Discourse is best implemented as follows. Create a subcategory called CV Database (or some other 2-word name you prefer), in which the About topic contains a link to the sheet in Drive. Clicking the link always takes the user to the current state of that spreadsheet.
If someone comes up with a CV to put in the DB, great. But there is likely to be a need to discuss the addition. An added column could optionally contain a link to the topic for that discussion. They might want to open discussion of it in Discourse. There might be disagreement; refinement or elaboration might be called for. They might learn something from the discussion; they might be wrong; they might worthily challenge some unexamined assumptions; and so on.
There could be other topics in the ‘CV Database’ topic, in addition to the About topic, if there were some discussion about the database itself, its organization, usage, etc.
As you suggest, it is also possible that discussion of what seem to be control phenomena can lead to specific CVs to put in the database.
For example, we’re speculating about what cats are perceiving and controlling in that video. Perceiving first, then controlling. Just limiting the discussion to vision, cats’ eyes work somewhat differently from ours. They greatly enhance night vision at the cost of being nearsighted ( 20/100-20/200), which serves them adequately as preferentially nocturnal predators. Wider field of view and binocular field about 130º vs 120º for humans, proportionally larger (8 inch diameter human eyes would be comparable), and in my brief foray into this I still have very little idea what difference it makes to have a vertical stripe (same as dogs) rather than fovea.
With humans, as we investigate higher in the hierarchy we find differences in how perceptions that by some criteria seem the same are constructed differently. I think you will enjoy Joel Stein’s In defense of elitism for one kind of example. (I read most of one chapter in my brother-in-law’s house, the 80-year-old birthday boy in the ‘skilled nursing center’, before his youngest brother glommed onto it.)
Because this is going to continue to grow over time, with more and more topics posted, and without the subcategories, you just get a longer and longer list of disorganized topics that gets harder and harder to navigate and engage with. Discussion is liable to slip from one issue to another in the same post, and we’ll have the jumbled and often mislabeled so-called threads of CSGnet all over again.
The purposes you propose for your “one general topic area – ‘Behavior of Organisms’” are actually the purposes of the Phenomena category. We could rename Phenomena as Behavior of Organisms. Personally, I prefer Phenomena, under the maxim “phenomena first”.
A Google search did show me a couple of attempts to integrate Google Drive sheets into Discourse. As an admin, I have scant interest in taking on more support risk, and I think one link from the About topic will serve just fine.
