Hi Greg
So our new index went up today. Looking at the last crawl date for www.easydigging.com we crawled the domain on 9/27 but did not crawl deep enough to find the original page containing the 301. So it may be a couple of more indexes before we crawl deeper to find it. What you would need to do help www.easydigging.com increase it's visibility/domain authority which will result in OSE finding more pages which will eventually find the link we need. The current page is no longer in our index as it not longer has any crawl authority and pretty soon it will not show any data in OSE unless it is re-crawled.
Once we can include "Just Discovered Links" into the main index, as Cyrus mentioned above, all you would need to do then is have any link tweeted from a high ranking account which will basically guarantee a crawl to that page.
