PineCone Research conducts online interviews with consumers to obtain opinions about new products and occasionally sends out products to try.  I have belonged to Pinecone for many years; now I trade points for gift cards.  To become a Pinecone Research panel member, you complete a short preliminary form (couple of questions) to see if there are openings for your group.  That’s so you don’t get surveys you get half-way through, only to find out you don’t quality.  phooey on those sites!
