I don't recall if Nintendo has one for switch, but off the top of my head I know PS4, XB1, and Steam do. There you can typically see when someone starts streaming, achievements, photos, videos, and more of what your friends list is currently doing. However, it has always been a feature I never use outside of stumbling into it on accident. I guess we could extend this to the Clubs and announcements aspects as well that these platforms use.
For me, I just never really see the point. I get my news on upcoming events from elsewhere and when i'm down to play, the last thing i'm doing is checking out the feed on what everyone else is up to. However, I will admit that seeing "XxSEPH1R0TH-sniperxX liked your recent activity" is always neat to see.
So how often do you use the activity feed? Are you someone that even checks them on your phone? I'm curious to see what ratio is here.
