I would hate it if the system removed nodes from my network without my influence. Perhaps a rules engine with user defined criteria would be useful.
Ultimately, users define their network in current-day social media and the relevance of any celebrity or other person within it.
400M people still find Selena Gomez relevant to themselves - she’s simply not relevant to you. I asked Gemini very simply “is Selena Gomez relevant” and it responded with essentially “more in 2026 than ever.”
Could potentially show you withering connections you havent interacted with, almost an auto recycle bin with the option to dig on there and bring it back later on but dissapear from your main radius of attention if withered.
Slack has started doing this in the last year or two - these are channels that you rarely interact with - want to leave?
Instagram has something like this where it shows you "least interacted with". It seems broken to me though, as it showed me people who I do interact with.
