That's actually a significant problem to overcome with the virality here -- the idea is complicated enough that it needs a solid paragraph or two to be explained, whereas for max virality it needs to be snappy enough to fit in 200 characters or so.

"Join this group to raise $20,000 for charity!" is normally a nearly ideal viral meme and in this case is true, but since 99.99% of things like this are fake people are annoyed by meme copy that is obviously not true, even though it is actually true. What I'm leaning towards now is something about "togetherness", how together we can make a difference or something. I am very open to suggestions on this point.
