found it odd to get friend request from people I really didn't have much interaction with
This! You'll just be surprised when they suddenly add you, I also experience that lol. But instead of feel bad, It will make me joy. I really want to see a lot of friend request in my list, but I won't confirm their request hahahat.
Ehhhh, most people are now of fb and the messenger is really helpful too to communicate with love ones.
As a family thing it was great. I basically ended my time when my account got hacked. Now I'm not really on any social networks, I have some accounts but zero to few friends.
