My T is also pretty blank slate, which I struggled with at first. But I have gotten past my transference (it took like a year) and now I see that for me, if T gave me more info on her life it probably wouldn't help me. However, every so often she will drop a little piece of info in passing, usually because it's related to our conversation -- stuff like a previous job, or something her friend said to her -- and I like that. It doesn't make the session about her rather than about me, and I like seeing those little tidbits of her life. I think if she told me more, I would want more and then it would fuel my transference and focus therapy on how I feel about her rather than about myself.
