I use lots of platforms for different reasons and don't really mind it much:
Instagram and Threads to interact with my friends, one for text content and the other for images. I can't really do that yet with Threads but the Zuck said he's gonna add a following-only feed soon.
Discord to chat with friends.
Lemmy for casual scrolling.
Twitter for when I'm incredibly bored and need to burn time.
WhatsApp to talk to family members.
I also have R*ddit installed but only to log in once a week or so and get the latest OPM chapter from r/onepunchman (and to repost it to the onepunchman Lemmy community).
Dunno about the thumbnails but it only shows you subscribers that are from your instance.
