I never understand the decision behind blogs not putting a link anywhere on their blog to their actual website. 1. Mixlr in the header points me to blog.mixlr.

I never understand the decision behind blogs not putting a link anywhere on their blog to their actual website. 1. Mixlr in the header points me to blog.mixlr.com. 2. Footer links, all of them link to the page I'm on... I know there is a link in the content of the post, but what about other posts? Why is there not an easy way for me to get to your main site without manually modifying the URL in the address bar?
