The subjects under discussion, at least those I choose to participate in, stimulate the mind. Come to think of it, do we even contemplate on a tenth of the topics we come across here on our own? I would say hardly. Forums such as this are living proof of the adage: "Knowledge multiplies when shared" . And if we ignore the occasional troll, the same holds for pleasure and happiness too. Which is what brings me here. I usually sign out smiling, notwithstanding my avatar's serious visage.
