Fred Wilson has a great post today on Squidoo and Squidwho . Squidoo is in the top 500 of all websites for traffic. It is similar to Wikipedia where individuals can create web pages on their area of expertise. Squidwhoo builds on the Squidoo platform as a directory of individuals listed on Squidoo and throughout the internet. It's an intersting example on the power of platforms and the ability to have others build web apps on top of them. Now it's time for me to skadoo.
