Cool Site Roundup

Mpire
Shopping sites rolled into one; similar to many comparison shopping sites but with a better interface

ShopStyle
Social networking and shopping; allows you to create profiles and share outfit ideas with others

SimpleWeather
Gives you info from Weather.com but without all the clutter

Etsy
Finest example of web 2.0 shopping; you can even shop by color

Miistation
A service that makes your Mii look more realistic (because who wants to play Wii Sports unless you have a Mii doppelganger?)

Hitchsters
Share cab rides with people that are going to the same destinations (still in beta for NY only)

SmittenKitchen
I've included this link purely for fun. I am a huge fan of food blog sites, and this one is far and away one of the coolest (the photography is fabulous!)
