There are certainly "favorite" websites. You could use that as "sites that I use for professional work and track the latest features." Gitlab, Github, Gmail, and so on.
There are also the "Mom's cooking blog" that is running an ancient copy of Wordpress and mom still doesn't understand that <b><i>This is important</b></i> is not formatted correctly. Some browsers are able to handle this, but if you browse it with a "this browser only follows standard compliant html" you may get the entire page in italics or bold.
The article even acknowledges this - https://awesomekling.github.io/Ladybird-a-new-cross-platform...
> Fidelity of modern websites in Ladybird is steadily improving, but you’ll often see lots of layout and compatibility issues. For example, here’s Reddit right now:
> (mangled layout)
We could put Reddit in that list of favorite sites that need to work. And so, is it the fault of reddit or the browser that the page isn't rendering right? As reddit works on other browsers, surely its the browser's fault and not something janky that reddit is doing that the other browsers happen to work with.
And thus my post - if a page works correctly in a different browser but incorrectly on Ladybird, to a user it is always the browser's fault.
