In TiddlyWiki tags aren't some kludgey text-based add-on -- they're built into the design from the first. Tags can contain spaces and non-Latin characters. Tags are available at the top of each note. Click on a tag and you instantly see all the other notes that share that tag. You can then change the order of that list simply by dragging and dropping from the tag-pill.

TiddlyWiki gives you the choice of whether you access additional resources (images, docx, pdfs) externally from the operating system or internally as embedded objects.
Cons
Con Subtasks only available in Pro version
Subtasks can break a longer to-do item into discrete tasks, helping you keep tabs on your progress.
Con Bad UI redesign
The web app takes up too much screen real estate and uses a half-screen format that requires a wide screen. The task edit screen is clunky. It still has UI bugs one year in. You can't complete tasks from the UI.
Con Free version lacks features
Mobile reminders, subtsaks, offline mode, Microsoft Outlook sync, priority, and more features are limited to the paid version ($39.99/year). To see the full list of restrictions, check out this page.
Con Does not support attachments
Cloud storage was recently added as a pro feature.
Con Cannot add task in notification bar
There is no pull down option to add a task in the notification bar.
Con Ugly icon
The goofy cow image does not fit well with a professsional office environment.
Con Too many backlinks can cause performance issues
With 100k+ notes, backlink and brain graph visualization can slow down the wiki.
Con Relies on browser performance, online or offline
TiddlyWiki is a single HTML file. Thus, if you directly embed e. g large images or videos in it (instead of using the features to display externally stored images and videos) it would make the file big and performance slow.
Con Without JavaScript nothing is visible
You need a browser that is not outdated to open the wiki, if you want to edit the HTML wiki file inside browser. Or you will need to download app like TiddlywikiDesktop or TidGi App to edit the wiki.
Con Unintuitive, complex official user interface
Too powerful for some new users, requires stribg ability to learn many interactions and advanced features sets. But this can be change at anytime by install community theme and plugins. Or use edition like TidGi app to get Notion style experience.
