Interacting with other goodreads members

I am not sure how to go about this, but I would like to interact more with other goodreads members. I am rather a shy person and don't like to arbitrally pick new friends at random as you might think that very presumptious on my part. Perhaps some of you out there might make a few suggestions, I would appreciate that. You might also suggest how I could make my blogs more interesting as well. Thanks
