Planetizen has a list of the top 10 websites for 2006. Check out some of them... I really liked Curating The City.. it is a great use of a living map.
Well google finally came out with their calendar... they have lots of great services including free web space and easy to use web page creation templates check out this page I made
Looking for a good online calendar that you can share... 30boxes is very cool ... I even like the name
I am usually a google person but Yahoo Local is very cool give it a try. Give it your location and you can see restaurant reviews etc for local places.
Zillow is "the" cool real estate link. Put in your house to see what the market price is. Mine seemed pretty accurate.
If you like beer there are many sites out there that have beer reviews but here is a new WEB 2.0 service called coastr it is sort of like del.icio.us except just for beer and places to drink beer.
