people expect encyclopedias to be able to tell them that there is one concept with two names.
I believe quite strongly that the concept identified with "move 'zig'" is exactly as real as the concept identified with "Let's Roll" and in fact the two are the same idea expressed to two different audiences. Furthermore, I suspect that defining "Let's Roll" *as* "move 'zig'" will tend to 1. prevent people from spreading either brand of crap into other areas of wiki and 2. very much help people not familiar with English or Engrish to understand each.
Policy on viral memes ought to be established early, as with references to risk and cognitive bias, which will otherwise creep into every single article.
The concept of "viral meme" is not a mainstream academic concept, and only merits the briefest mention in an encyclopedia. "Meme" is already treading on thin ground, but is at least well known enough to be semi-respectable. "Let's roll" isn't a concept at all--it's a phrase that has made the news recently, and it's the title of a song, both of which deserve to be covered. "Move zig" is another phrase, probably meaning more or less the same thing, but it isn't worthy of inclusion here. It isn't even a common enough idiom to be found in a dictionary--you certainly wouldn't find it, say, in a New York Times used without reference to its source. --LDC
