StoneyB explains what cotton-candy is quite well, and this interpretation makes a lot of sense, but the metaphor "cotton-candy view" can be interpreted in another way as well.
Cotton-candy is mostly consumed only by young children. Therefore it is sometimes associated with childishness or naïve...
Also, I remember that when I first saw naive, I thought it had two "I"s, like naiive.
Yawning I guess I should go to sleep. Bye! And, don't harvest all those alones without me!
