When I go to facebook.com and login I see this page (facebook-dot-com image). URL is facebook.com
When I click on the fish icon with my name (to right of facebook search box) I see this page (facebook-pattiefishicon).
The url changes to https://www.facebook.com/profile.php?id=1182919871
What is difference between the two? Are they 2 separate pages? If so can they be combined? There is much more activity on the facebook.com url than the one with my profile.
