I don’t think the fediverse has this, but I’m a bit confused why so many of these comments are puzzled at why you would want it. We have fediverse twitter, fediverse insta, fediverse reddit, fediverse discord, etc – why not fediverse facebook/myspace/carrd? Where users could just have small personal (or corporate) pages about themselves that aren’t as blog/news focused on the main(user) page.
I don’t even think it would be a huge stretch to implement: a big focus on user page customization with a small microblog interface taking up a portion of the screen would do it. (Disclaimer: not saying easy to create, just not that far out of reach vs everything else the fediverse has).
“Clobber” implies violence, which is somehow even less elegant than the standard phrase that the haphazard “cobble” implies. Given the shitshow of X so far, clobber probably works better even if it’s not the usual way to phrase this at all.
