What do you do with a personal domain?

bmerr71 writes: I bought my own domain name to use as a self-promotion tool. I use a subdomain, "profile.mydomain.com", which I selectively put on my email signatures to link to my linkedin profile. I also loaded up Google Apps to use for email. But when you go directly to my domain name, there is nothing there. I didn't want GoDaddy getting ad revenue off my name (and it doesn't look very professional), so I killed the ad page, but it seems like I should be able to put something up on my main page. But, I am not interesting in blogging, I do not want too much personal information up there, and I do not want to spend a lot of money (none, if possible). Are there any free apps that I can load up on my domain to fill the blank space? What do non-bloggers do with their personal domains?
