Pros
Pro Outline-style hierarchy with zoom

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. Tags can tag other tags, allowing you to create multiple types of TOC's with the built-in tag macros. You can create new notes tagged with the current note with just one click.

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 Doesn't work well in mobile browsers
The functionality of the mobile version of the site is a bit limited, while new features have been added such as the ability to move lines of text, even that is limited on Android to only being functional on Chrome.
Con Offline desktop app requires Chrome
The offline desktop requires installing Google Chrome first before the WorkFlowy app can be installed. This is not good news for non-Chrome users especially users who frequently uses Firefox or Safari as their default browsers, in which Chrome app also suffers memory leak and battery issues.
Con Inconvenient interface
Notes automatically collapse, making them unreadable without user interaction. You cannot view multiple long notes at once.
Con No public API
Con Cannot use link-text
You cannot have text link to a URL. When you link to a website you have to post the full URL instead. Instead of having the name of the website or article like, Slant, you instead have to post http://slant.co
. It's especially annoying if you have a long URL that takes up a lot of space in the document.
Con No support for Right-To-Left languages
Mixed text is scrambled, and text-alignment is wrong.
Con Doesn't work on all mobile phones
Not compatible with Android OS version 4.1 and 4.2.
Con Infrequent updates and new features
WorkFlowy works well but it is hardly ever updated, in comparison to Dynalist, which works in a very similar way but has more features and is updated weekly.
Con Only supports one big text file
Although with Workflowy's focus feature this can work, you might prefer managing separate text files.
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.
