A comment on yet another Rick-rolled post, this one of the Mario variation got me to thinking.

To quoteAemaeth:
Here at videosift, we go through fads where any video about a particular subject gets an automatic upvote from half the community. These videos get flooded over videosift to get some quick star points until we all get sick of them. Current popular topics include: Rick Astley, Scientology, and Obama. Past subjects include Ron Paul. Bashing Fox News or Bill O'Reilly is ALWAYS popular.

And so what I am wondering is how many different fads have passed through Videosift in the past two years?

Let's see how long we can make this list.
