I learnt that recently, apples co-founder Steve Wozniak advised that people should delete their facebook account.
I don't know why he said it, but I know that I have been planning to delete my facebook account for a longtime now. Facebook doesn't add any value to my life as such, but the reason why I have not deleted it yet is because of steem.
I get some inspiration on what to post about on steem from facebook, so that is why am taking time to delete facebook, but I know that at some point I will still delete facebook.
