Just lurk for a while.  I felt the same way when I first got here, I think Ann & ronb straighted my a** out.  I was looking for info and some guy was drunk on here... I think its histerical now.  The default topic around here seems to be booze LOL. But this place is on top of any breaking develpoements, ill tell you that!

Bottom line is you can find many knowledgeable people here (sorry im not one of them) you can join in or stay out of any topic.  You've asked some very legit questions that have been going around for some time now. Once you get a feel for this place its a really good DD, discussions and a TON of info coming through.  Im sure ts not for everyone
