Among the curious trend on the web lately, I am quite fascinated by YTMND:
YTMND, an acronym for "You're The Man Now, Dog!", is a website community that centers on the creation of YTMNDs, which are pages featuring a juxtaposition of a single image, optionally animated and/or tiled, along with large zooming text and a looping sound file. Most of these images are created or edited by users. Most YTMNDs are meant to expose or reflect the more inane facets of pop culture. Wikipedia definition)
Why do I blog this? I am always intrigued by some of the web trend regarding weird content reshaped by users. What is very powerful here is the level of private joke/common references those folks have.
My favorite is this one and of course the mac gyver one.
