You noticed something different when you looked at Twitter yesterday ( if you even login to the web interface anymore. Something. was. off.
Suddenly, it hits you; your carefully crafted wallpaper with links no one can click on is no longer there. Whaaaat?
Yes. It’s gone.
It is still visible on individual Tweet pages as well as list and collection pages, but if I were a betting man I’d say these will be gone soon enough. It’s inconsistent to not have it look the same on each page and it looks cleaner without it.
