I tend to be going in the direction of building specific applications, perhaps I would call this publishing TiddlyWiki instances, perhaps to provide online tools or take home applications...
... In these cases I expect them to be self contained and self documented
Whilst I wholeheartedly support promoting adoption through turn key solutions, easy adoption and well guided introductions to tiddlywikis capabilities, however I believe it must always expose its shear enormous benefits to an enthusiasts willing to "bite the bullet".
It sounds like you're talking about Editions.
One can imagine various TW's customized for Contact Management, Education, Recipes, Book Readers, Quizzing, Calendars, etc.
Tiddlyspot offers various aging custom solutions. Something like that but with a host of starter options would be cool.
Of course we can walk and chew gum at the same time and whilst I supoort complete solutions that answer peoples needs I also understand the limitations of editions. Many have inspired me, many have being a source of code and ideas but I do not use a single one everyday.
I have invested a lot to build my bespoke solution and I do not expect anyone to make the commitment, I know that the way I use it is not the way to increase adoption.
But I am not sure the direction you are going is the whole story.
To me it is the gap between what tiddlywiki can do and the effort to do it.
I speak from considerable expirence that the key in my view is we need to bring tiddlywikis features forward and exposed to novice users.
It is hard me to put the details of my argument because it is all about the details. yet also about retaining and expanding its pgilosophy and capabilities
Regardless of If get my ideas understood by this community I plan to deliver such improvements myself. Though some colaboration would be nice.
Examples include
simpler sopgisticated use of fields
generic queue managment features
simple note taking in a world of complexity
and much more
yours sincerly
