Donate/a/tweet is a platform we invented to be a social way to support the National September 11 Memorial & Museum, a nonprofit organization that's not federally funded. By typing a message on the homepage, you can donate $0.25 cents per character to the 9/11 Memorial. They will then tweet the message on your behalf with the #donateatweet and #911memorial hashtags and a shortlink to a personalized page with your tweet highlighted. The site was the museum's most effective social media fundraising campaign.
Here's a case study/walk through:
In the days leading up to the anniversary, we also displayed people's donated tweets live in Times Square, encouraging others to also donate.
