Quoted from fattdirk:
Interesting site, thanks for sharing. Wonder if they're trending based on the slope of the total or based upon the daily value. If you look at the daily values for some reason there was a reduction of 7.6k of donations last week? Wonder what caused that.
there was some joker who made a fake $10,000 contribution in order to get it to $66,666, and every time someone new contributed that person would adjust their amount downward to keep it at $66,666. i guess they thought it was funny. eventually that person cancelled their fake bid (or got banned), thus why total donations went down on that one day. the kickstarter is still well on track to make its goal.
