Here are my favorite things that I read on an almost daily basis:
Learn something new every day. The stories are short and interesting. The emails will help broaden your horizons.
Huge fan of Hugh McLeod. His books are great and the daily email makes a great afternoon boost.
Jason Hirschhorn’s MediaReDefined
The daily email is a great round-up of tech/music/interesting articles around the web.
Needs no explanation. Start reading it daily.
