I've been very wary of putting things in writing (even on forums such as this) for years now ... especially when I had to go through my mother's things when she passed away and found decades of letters and journal entries.  These were things that exposed her friend's secrets to whomever found these things and also her journals were filled with her pain and angst, and little else.  I threw it all away to protect her privacy.  

So, texting is problematic because you can't take it back and in a split second you can ruin someone's reputation or get attacked because of something either said intentionally or unintentionally and have the same result.
