I think the simplest option has been overlooked: just truncate “Tiddly”
TidWiki
- still has TW as an acronym
- Significant overlap with Tiddlywiki maintains a lot of the searchability. For me Tiddlywiki is the #1 result when i search for TidWiki. “TidWiki macros” still brings up macro documentation, etc.
- Tid is not offputting like Tiddly
- Tiddlers could be called Tidbits
- TID could become a backronym
- The In-Depth Wiki
- The Infinite Domain Wiki
- etc
Its a small change, it preserves the essence of the old name without being offputting, its shorter, and it doesn’t really break searchability so it could be rolled out ASAP.
