Hi all! I need some hair advice, and I'm no good at being objective about my own hair.

I have had a pixie, which I've loved, for a couple of years now. That's longer than I've had any one haircut, and I'm starting to get pretty bored with it. I've tweaked it a bit here and there, but still bored. Is that reason enough to grow it out? I'm thinking of the awkward bordering on terrible growing out period, here. I know it will take me 6-8 months to get where I want to be (a chin length bob, that's all I'm asking for! ;-))

I've included a pic of what my hair looks like now (excuse the no make-up), and here is a link to me with a short bob:

What do you think? And if I do grow it out, tips are appreciated. Does biotin really help it grow faster? Does anything?
