Personally I believe that is our respinsability When it comes to internet/social media.
Firstly, I would like to Say that If you have a Little doubt you can found other opportunities to show to your friends The places you go or share feelings, thoughts, whises with them.
For instance, you can choose from one of this:
-Send each one a view.
-write an email to all your friends.
One of this are privately than posting on online board.
Secondly, I want to add that I have different accounts and I don t Say that is a good ideea to have one, but I like to share more quiqly to everyone.
All in all, I agree The ideea of Having an account in these days.
