OMG, @newbee Stop being so damn polite! Just beat your chest exclaiming, “I am newbee. Hear me ROOOOOAAAAAAARRRR!!!”
Seriously. We don’t bite (very much). If you’re funny, all the better. Just don’t be funny until two or three answers are already up. After that, fun away! Silliness is something I would welcome, too (you’re right, people tend to be far too serious—although most would probably be surprised to hear me say it).
One thing worries me, though. If you stick around, you won’t be a newbie forever. But you’re stuck with your name forever! Well, maybe you’ll perpetually be getting newbie advice. Good luck! And welcome!
