The issue with “community” work is practical consensus rather than wind. Regarding SHOWCASES … just opinions right now …
1 - TW SHOWCASES need their own address (maybe under tiddlywiki.com/showcase ?) . Hence costs for doing that. Some one would have to design that and should be paid to do so.
2 - The showcases should be permanently archived (i.e not just be linked to) so the resource is reliably stable. This is partly where the money comes in. Someone has to get permissions to do that. It takes time. They could/should be paid to do that.
3 - Every showcase should have a statement about it’s remit, it’s purpose, on an index. Like “Anthropologist’s could use this …”; “Social historian’s could use this …”: “Bible scholar’s this …” etc. Get the idea? A brief mention of the purpose of each. Again this is where money is spent paying a “curator” to write that overview.
These are merely ideas.
