text: difference between a website and a portal. please be specific & crisp & to the point?   a web site is designed and posted to the internet.  the user/visitor has little to no say over what they see when they visit the site.  a portal allows the user/visitor to customize the view, thus requiring some sort of log in.  yahoo is run on portal software and is a great example.  what you see at my.yahoo.com is different then what i see.
