I feel like 5 years ago Twitter was really popular among st friends and we talked about things people tweeted, etc.
Since then I don't have a single friend who actively uses twitter, maybe it's that my preferences simply changed, but the overall visibility of twitter seems to be diminished.
I don't know, maybe its me getting older, but more digitally connected than ever and feel much less personally connected than ever except with the friends that I keep direct/group imessage conversations going with for months and years at a time.
Another personal example, IG direct messages aren't used that much from my experience (could be different for others or in the odd one). That few times I've been hit up or hit someone up on it, response or messages back and forth usually take forever. It kills the conversation. The only time a conversation has survived and a friendship began was when the convo quickly moved over to another medium (FBM in that case).
I do get your point though of feeling at home in a general sense.
I hear about announcements via twitter than then link to actual new stories and usually skip twitter entirely. Maybe I'm just not the right audience.
