Ultimate list of AJAXed Start pages / Home Pages. Though, 85% of the sites looks and does almost the same thing :/ . Inspired from one of the post at listible.
Live.com - One of the most Popular Start Page, from Microsoft. Clean and simple layout, MSN Messenger.
Google.com Personalized - Google’s version of Live.com. AJAXed nicely, supports Gmail Messenger, but only one login.
Start.com - Another AJAXed start Page from Microsoft much like Live.
MaxiGATE.com is a personal and social startpage that uses no module but can do anything. MAXI-gate -> “Maximalize Gateway”
SmileyToday - Smileys and lots of fun stuff like cursors, gossip with nice use of AJAX.
Magnoto.com - a start page which looks like a fridge and has magnets you stick on the fridge.
Home Portals - The real one Nice AJAX start page lots of features.
POPURLS - nice AJAX start page that allows you to see popular sites from digg, del.icio.us, furl and many others.
