Do yourselves a favor, put your blog at

When the ranking, search, linking gods do their super secret sauce algorithms, class="caps">PCGS.com will rank higher with the additional blog traffic. Also the links from the blog will be worth more to your customers and partners.

Think of it as adding to the reputation of class="caps">PCGS.com, not diluting it by trying to create another island.

It’s somewhat technical, but not too much. Your marketing team should know this.
