Google Reader is a web application that allows you to collate new posts from all your favorite web sites into one place and view it on your desktop or PDA/mobile phone.
Here's a sample of some of my favorite feeds that I read:

Questionable Content
A bunch of 20-somethings in a college town, and two personified computers.
Saturday Morning Breakfast Cereal
Surreal and ironic.

News about consumer issues; public shaming of bad companies.
