Sometimes you see something online and its kinda fun to play with and you kinda feel that its useful, but you are not quite sure how and for what ... here is the latest example: Squidoo.
So, anybody can go there and create what they call a "lens", a portal or a dashboard with various views, such as RSS, link lists or something else.
