why is Quora's question and answer site so complicated compared to Yahoo Answers question and answer site? anyone compared them?

Its not that Complicated the Set up is just different you just have to Play around with it for a while and get use to It 

another reason I will not be moving over to another site. 

I simply can't make heads or tails out of most of them, and  really don't care to try. 

I am content with the good run I had here, and that's ENOUGH of deranged stalkers in Cyber space for ME. 

I'll let someone else be the whipping boy  for whatever site my stalkers move to next. 

"Complicated" is subjective. Every Q&A site is going to be different, because they were designed by different people. If you want to know why Quora is designed as it is, as them (not the users of YA). 

Yes. Tried both Quora and Reddit in the last few days. Both are complicated and weird. But i guess we're gonna have to use one or the other.

Because yahoo answers was made before Quora. Quora has also updated itself over time while Yahoo has remained the same.
