Called Facebook.com/yalaYL, the site, created by a former Israeli diplomat and unambiguous about its links to Israel, has had 91,000 views in its first month. Of its 22,500 active users, 60 percent are Arabs — mostly Palestinians, followed by Egyptians, Jordanians, Tunisians, Moroccans, Lebanese and Saudis.

“All communication today is on the Internet — sex, war, business — why not peace?” asked Uri Savir, the president of the Peres Center for Peace and the founder of the new site. Mr. Savir was a chief peace negotiator for Israel in the 1990s as well as the director general of its Foreign Ministry and a member of Parliament. But he said he had never been more excited about a project.

“Today we have no brave leaders on either side, so I am turning to a new generation, the Tahrir Square and Facebook generation,” Mr. Savir, 58, said as he sat in his Tel Aviv apartment running his finger over his iPad to scroll through the site. “We need to emulate Tunisia. My goal is to have 100,000 people working on Yala on joint projects that will lock our leaders into making peace.”

The YL in the site’s name stands for young leaders (Yala means “let’s go” in Arabic), and Mr. Savir said he saw the page as a place where the next generation of regional innovators could meet. It helps that he has a few connections. The page has welcome messages from Shimon Peres, Israel’s president, and Mahmoud Abbas, the president of the Palestinian Authority, as well as from Tony Blair, the former British prime minister who serves as an international envoy to the Palestinians, and the actress Sharon Stone.

The site has already sponsored a photography contest — won by a Palestinian and an Israeli who will be flown to New York next month — and discussions are under way for sponsorship or involvement from the Italian government, the Barcelona soccer team and MTV. Mr. Peres and Mark Zuckerberg, Facebook’s founder, have chatted by phone about the effort.
