I personally think Tiddlywiki is a fascinating project and I even used it professionally for a few years. But, these days, I think you likely do better with either a Dropbox directory full of Markdown files or installing the free tool Simplenote everywhere (mobile/desktop) and using its support for notes/Markdown. It's true that if you go with these simple schemes, you lose wiki-style linking. But, I've found that YAGNI applies here.
