One of the great joys of reading blogs is the discovery of new voices with a different perspective on issues I care about.

Here’s an easy way to find some great marketing blogs that have already earned a following, but may be new to you. I call it Power 150 Roulette.

Todd Andrlik has compiled a Power 150 list of the “top” marketing blogs. Every weekend, I randomly pick three numbers between 1 and 150 and then I visit the blogs that are at these numbers on Todd’s Power 150 list.

For example, this weekend, I picked 30, 67 and 136. This led me to

The Viral Garden, where Mack Collier writes with insight and intelligence. He’s started a new corporate blog check up series. First up: Kodak.

adliterate, Richard Huntington’s perspective from the U.K. on “the future of advertising and the marketing communications industries, the impact of technology on communications and the nature of potent brands.” A mouthful. But worth visiting. A couple recent posts denounced brainstorms as the source of mediocre ideas and a reflection on the nature of advertising as a trade (spoiler: it’s not a profession and forget about training; learn on the job.) Provocative stuff.

Optimize & Prophecize, a take on Internet marketing from SEO veteran Jonathan Mendez. His post on Optimizing Social Media Landing Pages spoke directly to one of my current interests. I’m hooked.

If you haven’t taken a look at the Power 150, click over now. I discovered some great new blogs on Todd’s list. And I’ve subscribed to make many of them part of my daily reading.

Disclosure: I found the Power 150 and Todd’s blog when Pro PR showed up at number 111 on the current version of the list. Thanks Todd for creating this resource. I don’t know whether I’ll rank on future iterations of the list, but it was a pretty neat thing to find myself there at least for a little while.
