The document discusses New Zealand Blood Service's (NZBS) use of Facebook to promote blood donation. It notes that only 4% of New Zealand's adult population currently donates blood, yet demand is high. NZBS created a Facebook page to better communicate with and recruit younger donors aged 18-30. The page allows NZBS to update donors, thank donors, and raise awareness of donation needs and events. It has proven effective, with the page averaging 700 visitors and 52 new fans per week.
