Here’s a great resource for you, or a collection of resources, as you think through the marketing, identity, and focus factors that make up the heart of your plan.

It’s almost too big, but at least it’s divided into subsections, and it’s a great list. Thanks to Spotlight ID for this list of 250 top blog posts on advertising, marketing, media, and PR.

I got the tip on that list from Seth Godin’s blog post of last week, which started with that list, and then highlighted his top 20 favorites from his blog. He’s a clear winner in the top 250, and for good reason. You’ll find him referenced frequently in the plan-as-you-go approach (this site, and the book).

Add Duct Tape Marketing to that list (because I’ve referenced that in this site and the book too) and you have a lot of really good food for thought about your core marketing strategy.

These things go up and down, but I’m proud to share that — at least as I write this — The Plan-As-You-Go Business Plan is the number one ranking for business plan books at Amazon.com.
