about.me allows you to quickly build a personal and dynamic splash page that points visitors to your content from around the web. Want to know how many people are viewing your profile page? See how many people see your profile, where they're coming from, and what they do on your page.
I took 5 minutes to create my own profile page here: http://about.me/drjosephkim
If you're doing to use about.me, I would suggest linking to your LinkedIn profile, your Facebook page, and your Twitter account. about.me is currently a free service (but that could change in the future).
