There is more than one answer to this question, depending on why you write on hubpges. I can only answer for myself.
One reason I love writing here is because of the immense growth I have seen in my own writing. I learn and am both inspired and motivated by other writers.
The comments are crucial to my learning and growth. The support I recieve is like a "shot in the arm".
The vast amount of friends, love and strenght I have found here, can't be matched anywhere else.
I am truly blessed, as we all are, to be writing here on hubpages!
