A while back, I started an Instagram for my family history, so that I could share neat photos easily: https://www.instagram.com/findingwhanau/
More recently, I returned to Twitter because a group of lovely genealogy buffs are doing an ANZ Ancestry q&a/chat session on the 6th of Oct & I’m keen to participate: https://twitter.com/findingwhanau
I also use Facebook fairly regularly, although that’s more private. But I’m happy to add family members, so drop me an email to discuss.
