Around 4:30 p.m. ET on Tuesday, Twitter took the much-circulated hashtag, #OneBoston, and gave it the Promoted Trend slot pro bono. Viewers who click through the ad will see a tweet from Boston mayor Tom Menino, and then they can access a donation page to help the victims of yesterday's unthinkable marathon tragedy.
Some folks tweeting #OneBoston are pointing to other charitable efforts for Monday's victims. Placing the hashtag in the normally expensive ad slot will increase traffic to all of the donations sites and other goodwill initiatives.
