How would one get on the Huff Po's "Around the Web" list?

[AdoptionHelp]

On the huffington post they often have lists of links related to the article, near the bottom just before the comments. This section, when present, is called "Around the Web".

See this as an example: http://www.huffingtonpost.com/linda-bacon-phd-ma-ma/health-at-every-size_b_1314339.html

Do the article authors choose these links, or are they auto-generated somehow? I had a relatively small competitor appear here, so I'm wondering if there are any tricks to gett included.

Thanks!

While I can't say for certain (and Google searches were completely unhelpful), I'd bet that these links come from partnership / content share deals that HuffPo (or AOL) has made with the sources that show up in those links.
