I like the direct you're going with this. #5 is interesting. I'm wondering if you can somehow, someway, weave in the different types of topics that our website will be discussing (marketing, sales, web software, productivity, etc.)
Not sure exactly how you would do. Also, would like to see different types choices and colors.
Remember, this website will have a business feel to it. The resources are for business owners and executives to help them generate more ROI and ultimately profit. So, those elements should be come through in the logo -- if that helps.
