I've always struggled with what to put at my root domain. Mainly because some hosting providers don't really let wordpress work on a base domain, typically ones that don't use cpanel for their subdomains. One of my prior hosts used frames to do subdomains which was really annoying so if you enabled it then you couldn't do anything really with the root cause it was basically just a redirect portal.
Lunarpages lets me put wordpress in so I installed wordpress at my root and now have a life stream which can and will pull in all my online activity to it, as well as provide a landing page for me (and my "users") to use to go to various other sites located on my domain and other useful links I need regularly.
So now I have a working front page with useful information and the potential to do more. I'm thinking of adding in my WoW characters as there is a wow armory link that is really cool thus far. It is something I wanted to do as well. I might do that as well for Shea since he's been bugging me again about a webpage lol.
