why we never find interesting people on this site?

Because you are stupid or just plain new here.

I think there are many interesting people here.

Yahoo Answers has always been the worst platform.  Back in the day , The Huffington Post was truly impressive , before Arianna Huffington broke her promise to her subscribers. 

 "HuffandPuff" was kinda like sitting in on a discussion group with nothing but PhD's and Science Majors. And the art of the written word offered by many subscribers , was like touring a fine art exhibit. The abundance of literary talent , was amazing.  If you have ever experienced the joy of an informed , educated and objective debate , you know  how exciting that can be.  Regardless of your own position on a particular subject. 

All that changed when the www decided to reject a members right to remain anonymous.  We HuffPost refugees knew the potential personal risk of publishing our innermost and honest opinions on the www , so most of us found other platforms.  I ended up here because when I signed up for a Yahoo account , I didn't need to provide a valid phone number , or real name. 

As as result , I  don't have pick-up trucks loaded with TrumpSuking Thugs flying TRUMP / PENCE flags circling my home. 

Cause you ignore the interesting people.

Try twitter, but be really careful what you say or you could be canceled.
