[26] In a 2010 interview with The Link, the magazine published by Americans for Middle East Understanding, Philip Weiss described the evolution of Mondoweiss: In March 2006 I began writing a daily blog on The New York Observer website.

[27]In The American Conservative, Weiss detailed his split from The New York Observer and wrote, "Blogging about such matters sometimes made me feel wicked, as though I was betraying my tribe.

Wolcott quoted Weiss who had written: "It's happened: the Anti-Defamation League has overplayed its hand (in this case, neoconservative Islamophobia) in such a glaring manner that it is being condemned at every quarter.

"[33][34] In 2012, Tablet magazine wrote that the Associated Press had "picked up a story from advocacy blog" Mondoweiss,[35] about Israeli security asking a Palestinian-American to show them her email at Ben-Gurion Airport.

[35][36] In 2012, Mondoweiss reported that United States Representative Joseph R. Pitts' office had mailed a letter calling on Israeli Prime Minister Ariel Sharon and Palestine National Authority Chair Yasser Arafat to work toward peace in the Middle East.

[38][39] In March 2007, Gary Kamiya, in an article for the website Salon, wrote that Mondoweiss offered "informed and passionate discussions" of what Weiss stated were "delicate and controversial matters surrounding American Jewish identity and Israel".

[40] In 2009, Michael Massing, in an article titled "The News About the Internet" for The New York Review of Books, noted that "Weiss is one of several friends I've seen flourish online after enduring years of frustration writing for magazines.

"[41] In November 2009 former United States Senator James G. Abourezk praised Weiss and Horowitz for their courage in taking on "what most believe is an unassailable, monolithic pro-Israel Lobby".

Mondoweiss is evidence that more and more American Jews are thinking twice about giving Israel their wholehearted, unquestioning support for the crimes it is committing in the territories it illegally occupies.

"[42] In September 2010, James Wolcott of Vanity Fair argued that Mondoweiss "is one of the most invaluable sites in the blogosphere, a blast of sanity and moral suasion against the prevailing demonization of anything and anyone perceived as anti-Israel".

[52][53] Armin Rosen, a Media Fellow with The Atlantic, criticized Peter Beinart's blog, Open Zion (which appears in The Daily Beast) for publishing an article by Alex Kane because he is Mondoweiss's "Staff Reporter".

[60] Journalist Bradley Burston, writing for Haaretz, described Mondoweiss as "avowedly anti-Israel" in reference to its coverage of the 2014 kidnapping and murder of Israeli teenagers.

This included Weiss' claim that "the Israel lobby ... reflected a contract the American establishment had made with Jews to drive the economy in the 1970s",[62] which Bernstein likened to a belief in an "Elders of Zion type group".
