Hi Jacob,
This isn't uncommon. OSE and Mozscape crawl the web and do their best to report on links most likely to influence rankings and traffic, but they don't report all links. The latest index, I believe, is around 90 Billion links. It's a pretty good index, but we can do better, and have plans to do better going forward:

We do a good job of finding/reporting the most important links on the web, but sometimes we miss a few links on less popular pages.
My friend Aaron Wheeler gave this explanation of how our crawlers work:
"We update our Linkscape Index every 3 to 5 weeks. Crawling the whole internet to look for links takes 2-3 weeks. And then we’ve got 1-2 weeks of processing to do on those links to determine which are the most important links etc. You can see a schedule of how often we update, and planned updates here.
Linkscape focuses on a breadth-first approach, and thus we nearly always have content from the homepage of websites, externally linked-to pages and pages higher up in a site’s information hierarchy. However, deep pages that are buried beneath many layers of navigation are sometimes missed and it may be several index updates before we catch all of these.
If our crawlers or data sources are blocked from reaching those URLs, they may not be included in our index (though links that points to those pages will still be available). Finally, the URLs seen by Linkscape must be linked-to by other documents on the web or our index will not include them.
I hope this information helps! While the site may not be indexed yet, give it some time – maybe we’ll see it in OSE and Linkscape next month.
Best of luck!
Aaron"
