Totally TER Related!! w/an added tid-bit.........

I dunno if posting in general is the right place for this, but I am Not a "Social Media Butterfly", Can I get some inside information on how these Social media Icons displayed on here play into our so called "private world"?
It may be nothing, but seeing them on display has me a lil' on edge and wonder if what we display here can be seen on live feeds like tweets?
meaning, if there is an ongoing thread and someone wants to post it using tweet, can it be done?
or same as photo threads or when a lady posts a video on her ad, can they pick it up with their devices and tweet away to whoever they want to share it with, and next thing we know our private conversations are on live display?

Please don't reply with rude comments, I am just concerned as how TER icons are being used through our social networks and how safe they are as we use them!!

Thanx!! to all that can help put my mind at an ease when posting naughty thoughts
