So what is TW? I agree it’s not a multi-user note-sharing system, even if my comparison refers to such apps.
TW is certainly a kind of meta-wiki because you can go as far as to create apps or games, to a reasonable extent. Its scripting puts it way above tools like Notion in terms of capabilities, but the bareness makes it a hard sell.
But at it’s also a simple personal wiki, as you can never touch the scripting an be happy creating wikitext-only tiddlers and link them together.
And while @Mark_S is right that it’s not a multi-user note-sharing system, the plugin capabilities certainly allow you to get very close.
We could seek the answer to the question on the frontpage of TW:
Welcome to TiddlyWiki, a unique non-linear notebook for capturing, organising and sharing complex information.
But I personally have hard time understanding this description and the way I understand it it sells its capabilities short.
I have no answer, I’d rather hear what people who have more experience with TW to tell me how they’d define TW. Because I think knowing that is important in determining what, if any, steps could be taken to make it more appealing to new users (or get me to buzz off from all these complaining ).
And if I were to put a marketing blurb on TW I’d go with something like this:
A notebook or todo.
A personal wiki or customizable web app.
Tiddly Wiki gives you power to do it all.
