Well, I just set my account to Private, because the jerks at shello.co (/cc @ralf) put me on some public list of People to Follow or People That A Lot of People Follow or whatever.
We've known for a dozen years what dynamics this creates -- preferential connectivity drives the 'rich get richer' effect through the roof, and you stop having 'people hanging out where you are hanging out' and you start having followers, which, if I want to be in a place where I have followers, there's a whole service just for that you may already have heard of.
All of which makes me sad. The people willing to participate in a place that has no obvious purpose or goal has been wonderful, but looky-loos have always outnumbered participants 100>1 (h/t Bradley Horowitz), and the two moves in two days -- share and now search (both of which I've dreaded) make me think that there may simply be no way to have a social medium that is based on the long-term value of inconvenience.
Sharing something from here should take some work, to keep it high signal and low-flow, but the demand for incremental automation moves us, step by step, to a world of high flow and low signal. /cc @cacheflowe.
