I have been using Facebook for years now the reason it being simple and efficient. It is one of the best way to keep in touch with your friends and families.
One of the reason why I like Facebook is you can keep track of your own activities its like looking into yourself and your activities done in the past making you to cherish your memories.
You can chat and do video or voice call to anyone in your friend-list and my personal experience has been very good.
Lot of fake ids and request recently is bit annoying and people using various post to advertise their product is also frustrating. But various policy and privacy of the website makes it best you can decide who can view your post, profile and who can send you request etc. The world is on Facebook I would suggest every person not on Facebook to immediately give a try a MUST TRY APP.
