In an attempt to encourage people donate blood more regularly in Brazil, a unique social donation campaign was set up by the Red Cross Pernambuco. 'Tweet Donate' has users visit the campaign site and type a message to share on Twitter as usual. For those who don't manage to use up the 140 character maximum that Twitter allows, Tweet Donate fills in the rest to spread awareness about the importance of donating blood. With space available, messages that are tacked onto tweets include tags like #doetweet and #tweetdonate, as well as shortened links directing other Twitter users back to the site.

The site keeps a tab on the number of characters that have been donated—well over 35,500—showing just how easy it is to share the message and donate blood.
