In some sense, they must get a lot of bot traffic who only scrape the site to see what's "hot" because BuzzFeed itself is a highly optimized version of Yahoo Popular News. And BuzzFeed probably has little incentive to police these bots because that would drive their pageview numbers lower. At the end of the day, they probably have low value traffic and their ads sell cheap. But the BuzzFeed is probably not too concern about CPM because when the do sell they will try to frame the valuation around pageviews and not revenues.
That would be a really, really weird choice. Facebook has an incredible number of editorial partners, I doubt they'd be too happy if Facebook bought one of their competitors.
The comment by danso in this thread highlights the problem with this dream pretty well:

They have a strong brand perception they will need to overcome if they truly want to become a trusted news source. They've been very successful at becoming an ubiquitous and constant presence across my Facebook news feed, but I've never seen anything beyond the standard lists.
I read a lot of longform content, but I never considered BuzzFeed as a source due to its reputation as a pusher of repurposed Reddit threads and "viral" content. I probably owe it a second look
You'll also discover they had a viral hit with blackpeopleloveus.com from back in the day, if you didn't know that already. So Jonah's viral chops pre-date HuffPo.
On a related note, I kind of wish that HN would remove its blanket ban of the Buzzfeed domain. Their longform section has as great of HN-likable original content as any other legit site: http://www.buzzfeed.com/longform
Users should still exercise the right to flag the Buzzfeed list crap off of HN...but let's face it, with the numbers at Buzzfeed claims, the HN bump would merely be a blip for them.
