That said, I advise against Tiddly Wiki, after using it for long. It has multiple bugs, which the author won't fix (e.g. div's inside p's), It has a cryptic syntax (e.g. code in attribute values), and tagging is not implemented in a way which makes a wiki scale (well, technically it is, tags can have tags). It is a thing where features are added but nothing outdated gets deprecated, so it is bloated. One will be more productive by using a folder with markdown files, and a browser add-on like Markdown Viewer.
I don't know, for me it works, but I don't do anything fancy with it. I just put it on a server, so I can access it from all my devices. I don't even use tags, just tiddlers with sources which are other tiddlers or external web pages.
My solution to a lot of issues is to use Tiddlywiki Classic. No divs inside p that I can find, less bloat (412 KB for a blank file instead of 2.5 MB), and it's still maintained. The main advantage, to me, is that it fits more tiddlers on screen at a time, which is the main point of TiddlyWiki for me; TW5 adds large amounts of spacing, borders, and large font sizes, which looks nicer but is less practical.
It's not perfect, though. Paragraphs are rendered by using two br tags, instead of p tags. Link syntax is the reverse of MediaWiki syntax; i.e. [[foo|bar]] links to "foo" in MediaWiki, but "bar" on TiddlyWiki, which trips me up constantly. There's other syntax awkwardness like sensitivity to spacing and newlines. Journals sort in alphabetical, not chronological order.
