Lots of questions there! You are a curious one, aren't you! :)
Some people do write less in their intros because they think it's like revealing too much about them on the Internet - my friend thinks that way.
I prefer to share what is as it is. And it's always been fun, you know - to connect, share, and engage with new folks... online or offline. :)
Same here. :) I'd like to share as much as I can.
