Coolest web app I have seen in a while. If you like books, you'll love this:

I asked my Twitter followers who the smartest people they read regularly are. These are the answers.

"Readers are smart, and they love to read, and they’ll go where they can read, and they have more and more options."

"If you’re writing for the right person, everything else become natural and easy." -Who Reads For You? by Randy Murray

"If you’ve decided that you want to read, Marco’s app will really help you. He’s removed any phony barriers you’ve built about “not having time” or “not having it with you” or “not knowing where to put it.” There are no excuses, apart from the superficial animated ones you’ve constructed out of cartoon birds."

A great solution would be a service or plugin that categorizes everything based on reading time. At the most basic level, this would be calculated by the word count. There are already a number of plugins for WordPress that accomplish this1, and it can be done with less than 10 lines of PHP.

The universe is filled with endlessly fascinating things. You could spend all of your days jumping from one thing to the next. And you can spend hours here and there surfing from topic to topic.

Or you can spend an hour reading, exploring something in depth.
