We're jazzed to find ourselves on this distinguished list. Evan Carmichael does a very credible and thorough job providing motivation and strategies for entrepreneurs.
Since we're talking productivity, here are some of my "must reads" when it comes to organizational life and productivity:
Wally Bock at Three Star Leadership. This is where you'll find the "how to" of developing managers along with experience and depth of thought to support the suggestions. He also analyzes the business news of the day in ways that make it meaningful to office and cube dwellers everywhere. Wally, quite simply, knows his stuff.
Jim Stroup examines issues of Managing Leadership from every angle and every level in organizations. When he gets on a roll with a topical series, I don't miss a post.
You'll never think of presentations and design the same way again after following the guidance of Garr Reynolds at Presentatation Zen.
For blogging tips and resources that flow throughout the day, ConverStation's Mike Sansone is in my reader.
