Recently I've been a bit frustrated when visiting the pages of Facebook friends and not being able to easily get to their blogs or websites. It is very easy to display websites in the Basic Information:
1. Go to your Profile page. (Note: these steps are written using New Facebook)
2. Click the Edit icon next to the Basic Information section (the "pencil").
3. Select which options to display or not to display.
4. When finished click on another section of the page to close the Edit dialog.
If you are not sure how to add/remove information which appears in the Basic Information section, on the Profile page, click the Info tab. Select the area to edit and again click the Edit icon.
