Tis the season for giving... blood that is. MaxPitch Media, the publisher of justsell.com, has launched a global blood drive, dubbed The Global Sales Blood Drive. Its goal is to inspire sales professionals to go to www.salesblood.org and pledge their intention to donate blood. Sam Parker, cofounder and publisher of MaxPitch, leveraged its subscriber base to get the word out, but he hopes that this initiative will prompt other professional groups to check out the site and use tools found there to spread the word and to pledge their own intention for giving blood. The event is taking place now through Dec. 2.
