For a company, your welcome page should clearly state
WHO your company is, WHAT you do, and WHERE you are located.

For an individual, go nuts! This is where we can quickly learn more
about you and what your interests are. Keep in mind these interests
will be what people will use to determine whether they want to stay
at your site or not. So be specific!

Avoid putting links (going off your site) on this page. After all,
you've worked hard to get people here, don't let them get away!
