I agree with Larry on this to an extent, but Twitter is just so open. Anything you post on twitter, unless you lock it down, is basically public domain. Even people who do not follow you can find you and your info and all your tweets with a simple google search.
A word to the wise. Nobody should consider sharing anything on here that they would not want their enemies to see. Even consider the friends you have on here as a potential threat, because all it takes is one disagreement to get it thrown in your face. Also, the username you use on here should be different than your social media usernames. Keep it different and then you will keep your privacy.
I have a huge amount of respect for many people on here. many I consider friends. I still have to keep up walls though. It just has to be that way. Everyone should have their guard up some.
