Audiomack also has an interesting similar solution by including it in the sidebar.
Nice! I like that solution.
Not sure this counts as a real "solution": They only have this side-footer on the home page and no footer under articles at all. Also, this only works if you have almost no content in there, for everything else this wouldn't work.
Good thing to keep in mind for sure, but only working for very specific use cases.
Yes. That's true. It's limited to specific use cases.
Airbnb's approach is pretty good: https://imgur.com/a/DdOvqMy
That's great and everything but they desperately need to fix threaded comments. Each comment is posted as an individual story and to follow a thread of comments is almost impossible, it's really nasty.
Have you tried using Facebook or Twitter?
Facebook uses this pattern but it's not an actual footer because their widget stays fixed to the top of the screen. Users would have more trouble identifying that as the footer.
It's a subtle difference but Medium's implementation stays fixed to the bottom, which makes their approach visually and layout-wise more similar to an actual footer. Their pseudo-footer is spatially closer to where an actual footer is supposed to be and this makes it easier to find and distinguish from other navigational elements.
Twitter doesn't use this pattern. They keep the footer under the "Who to follow" widget, but that widget is not a sticky widget.
Once you are several screen folds down, there's no way to see the side footer anymore. You need to scroll up to the top again. I always wondered why they did it like that. Their feed has a lot of available screen real estate on both sides. I would have recommended keeping that widget sticky, but I'm sure they have a reason.
