1 - It’s unit (Tiddlers), from micro-mini to mega-massive size, is the foundational architecture that provides the basis for it’s huge flexibility of applications.
2 - It’s understanding a “unit” (Tiddler) that could be code, markup, reflexive self-examination, an image, multi-level nested transclusion, scripts and anything else the net can do.
3 - It’s agnostic remit that leaves doors fully open for end-users. (It is not software committed to any specific theory of knowledge.)
4 - It’s acceptance of multiple methods and computing philosophies is very unusual.
5 - It’s method of saving itself that is a whole altering itself as it saves itself to its new whole. (Technically that is the behaviour of a rare practical Quine.)
6 - It’s huge scalability—as an entailment of (1), (2), (3), (4) & (5).
