I know this is nitpicky but the logo on your blog should be linked to your home page, not back to the blog.
The purpose of the blog is to promote your company/product.
When I visit your blog, I am now curious about what your product/service is. I expect to be able to click on the logo and find out about your company/product/service.
Linking the logo back to the blog itself is a missed opportunity to increase sales/marketing.
I'm curious about your product, but at first my curiosity is very low - I am willing to spend enough effort to click on the logo, but I am probably not curious enough to then go hunting to find your home page after the link sends me back to the blog.
A potential customer being willing to click one link on your site has significant value - don't squander it.
