At first, I thought the same thing too, but, to be fair, this is a site that clearly caters to people who are familiar with acronym and the associated activity. As such, it might not be a good candidate for posting here, and there is no reason why every site should be. In this case, the free sample issue of the magazine, linked to elsewhere in these comments by somethingsaid, would seem to be a better introduction.
In my experience here, people sometimes appreciate a bit of a puzzle and the opportunity for discovery, the results of which they then post in the comments. What topic fits that better than this form of blurry photography, where even the name is ambiguous?
