One of the best things about Hub pages is that no one is setting standards for others about what they should be doing here. I believe that you enjoy socializing, so good for you, enjoy it. What surprises me just a bit is that you find it unusual that somebody else may have a passion to write hubs. I have done 100 of them over 4 months since I started, and the number is not important to me, it's the challenge of putting some thoughts together that others may find interesting. Well, to be honest about it, I am happy and proud that the number came to100, but again, it's not about the number. - I certainly wish you a lots of fun at socializing on Twitter and Facebook.
I don't know about "testosterone". If you don't mind some humour, it's more of women's fun to chat back and forth, so an excess of "estrogen" would be more likely.
