Hence, today’s brief flurry of reports echoing Radar Online’s scoop that Supreme Court Chief Justice John Roberts was “seriously considering stepping down” for “personal reasons.”

The story, which was published early this morning, is not true. And it was ignored until lunchtime on the East Coast, when the Drudge Report picked it up. At that point it became open game for a host of smaller sites, which picked it up with varying degrees of credulity.

Radar has since reversed the story, noting that it “has obtained new information that Justice Roberts will NOT resign. The justice will be staying on the bench.” The site has yet to update its headline, though, which is still trumpeting its “exclusive.”

Radar is a media gossip site/magazine that has gone through several permutations over the years. In its current incarnation, it’s an online-only property owned by American Media Inc., the people who bring you the National Enquirer, among other properties.

But while the Enquirer has a history of getting some big political stories right over the years, Radar doesn’t. It generally sticks to stuff like photos of the “Jersey Shore” dudes taking off their clothes. Probably a good strategy going forward.

BoomTown has known about it forever and Radar Online gave the lowdown about the creation of the hip-sounding news aggregator Web site–headed by high-profile editor Tina Brown (pictured here)–by Barry Diller’s IAC (IACI) in a report in early April.

Think the Huffington Post, but more culture and less political wonkishness in a bolder and more colorful design.

While still in its planning stages, though, it just hired a new GM to run the business: Caroline Marks.

She was GM of Comcast’s Ziddio, a social video endeavor, and was also head of content development for Comcast Interactive (CMCSA). Marks has also worked in several high-profile mobile companies in the U.K.

Marks will reports to IAC’s Nick Lehman–who works for Michael Jackson, the head of programming at IAC–to get the project off the ground for IAC and Brown, the former Talk, Vanity Fair and New Yorker editor.

The project has already hired Edward Felsenthal, the former deputy managing editor of The Wall Street Journal (and BoomTown friend), to helm the edit side under Brown.

IAC has dabbled a lot in online content initiatives of late with mixed results. Still, it is moving forward with even more.

For example, the company is set to debut a personal financial site in a joint venture with News Corp.’s (NWS) Dow Jones (owner of this site), called FiLife, in June.
