I have my own site but I can never decide what to put there or how to design it so it mostly just links to various places around the web that I am or have been. I do host things I link to from my journal there, but that's about it. My main reason for having it is to keep a static email address regardless of where I go.
In an effort to minimize profile duplication I recommend reading my OkCupid profile to learn more about me.
