Recency bias and normie influence. If someone was laughing their ass off about Hasan this week, it's going to be a stronger memory than laughing about Austin in July and getting nothing since then. Hasan has memes all over the internet mocking him, like it or not he's a bigger lolcow at the moment than Austin who we haven't seen in months. The average redditor knows who Hasan is but does not know who Austin is.
He's going to have to get a wife, have three kids and have a meltdown that attracts the attention of the mainstream news before the end of this year to even have a chance. You have to have a rise and fall type situation since most people come to this site from those videos.
