And Google has additional ways to identify sites all related, such as everything in the same GWT account, sites having the same Google Analytics master account, etc. Doesn't mean they use it for ranking, but they have ways beyond just IP to see things are related.

Thanks for letting us know Jeff, that's great to hear!

FYI, your keyword targeted link is a nofollow link, as are all hyperlinks in Q&A and blog comments on SEOmoz.

OSE will download up to 25 links from a single domain. Are some of those site-wide links in a footer perhaps?

We're aiming to have it out next week!

This may be a good case for a private question, as the SEOmoz staff and associates are under NDA and you can share a few more details.

If it's to avoid orphaning, does this mean that they otherwise have nothing internal linking to them and that it's expected for people to go to the site map of 5000 URLs to find them?
