Meredith Bowen was getting tired of requests from Facebook friends to exchange make-believe pansies, daffodils and tiny cartoon characters for her "(Lil) Green Patch," a virtual garden that sprouted on her social-networking page about a year ago.
She was ready to delete it, until she learned The Nature Conservancy was getting a portion of the ad revenue generated by the game.
"I've saved like 133 square feet of rainforest," the 31-year-old Holt resident said.
Bowen illustrates both the potential upside and downside for charitable causes hoping to cash in on the popularity of social-networking sites such as Facebook and News Corp.'s MySpace.
With millions of users worldwide, the sites would seem fertile ground for fundraising experiments — especially ones where users aren't asked to make direct contributions.
But it's far from certain that social networking will prove as effective as more traditional fundraising methods such as direct mail, telephone solicitation and even e-mails to past donors.
One hurdle to overcome is the sheer deluge of information online.
As Facebook users are bombarded with invitations to send and receive virtual beers, throw snowballs, sign petitions and take quizzes, applications benefiting charities can seem like just another silly game.
"I get so many of those requests," said Nicole Marble, 23, who works at Michigan State University. "Sometimes I pay attention to them, but with a lot of them I'm just clicking 'Ignore, Ignore, Ignore."'
She took only minor interest in (Lil) Green Patch until learning recently from a reporter that the game's promise to help save rainforests and fight global warming was genuine.
"I'll probably look into it a little more now," Marble said. "I just finished tending my garden, whatever that really means."
Many appeals on social networks have drawn lots of attention but few dollars.
"You often see where 20,000 people have joined a cause and it's raised $200," said Jim Tobin, president of Ignite Social Media, a promotional company in Cary, N.C.
The (Lil) Green Patch game has done better than most, generating $162,150 in little more than a year, said Sue Citro, digital membership director for The Nature Conservancy. It is among the most popular applications that Facebook can add to their profiles, with nearly 6 million active users monthly, according to Facebook.
Players plant virtual "gardens" with flowers and fruits sent by friends and send plants to them in return. Ads are shown alongside the game. Green Patch, the Mountain View, Calif., developer of the game, donates a portion of ad revenue to The Nature Conservancy's rainforest preservation campaign.
It's yet another avenue for raising money and awareness, supplementing direct online contributions generated by running ads and sending e-mail to past donors. Social networks can potentially be more effective because they are cheaper and involve referrals from friends.
"A lot of the world is transitioning to using not just the Internet, but the socially connected Internet," said David King, Green Patch's founder. "We see this as the beginning of a whole movement where people are able to connect with each other and with foundations representing the causes that are important to them."
