As I mentioned in a comment here, others have emailed this to me and the versions I saw all cited reddit pretty overtly and provided links. I think it's an interesting phenomenon that has been occurring around tweets for some time now and it appears reddit is now a part of it, even beyond the Daily Dot. But I think the reason to not just link to the reddit post is that these publications have (conceivably) edited out all the crappy jokes.
Don't get me wrong, I think the whole "repackaging social media as journalism" thing is pretty weak. Are the jokes they chose the top ones from the post or did they do some digging? Either way wouldn't surprise me.
I'd love to see whether or not Hubski can influence the popular/public consciousness. Hopefully not for tiger pictures though.
