For stickers and elsewhere, good slogans will be an important thing.
Here are some besides "the anti-social networking site"
"The End Of Life As We Hate It..."
"Have-nots, want-something-for-nothings and blame-America-firsters" (from a speech a friend of mine's sargent gave about protesters).
"When we whine together, we'll shake the world..."
That's just for starters, more ideas welcome...
