Let's say I create a new gmail account under a pen name, and create a blog with blogger.com, and I publicize it a lot under that pen name, and let's say it gains a following of several million people, and someone (or more than one) wants to know who's the real person behind it. If I created the gmail account and blog on my regular computer, will they be able to track it to me somehow? Should I create the blog on a university computer? Should I never log in from my computer? How does this stuff work? How secure is it? Thanks!
