Would you share some else’s family photo tweet? Would you still share the photo if you didn’t know the family in question? Most probably you wouldn’t share it. I wouldn’t either, and here is the reason. Twitter is a bit sensitive to personal and family private lives. People tend to interact on social things that are non-personal. After all, most people barely know their follows on person to person basis. However, other than automatic likes, family photo posts do attract a high number of likes. In fact, more often than not, family related tweets attract a higher number of favorites than there are automatic likes.
On another note, very few people love it when pictures of their private lives get to trend on social media. But then, that does it mean that is wrong to post anything about your personal life? No it’s not. In fact twitter is not always about professional topics. It is also not all about jokes and roasting public figures. Sometimes you may share something you do on your private life and ask people to give their comments about it. This way you get more likes than just posting selfies.
