NEW YORK (Reuters) - The chief executive of social media platform Parler, popular with American right-wing users but which virtually vanished after the U.S. Capitol riot, posted a brief message on the company's website. Parler's app, however, remains offline.

"Hello world, is this thing on?," Matze asked in a message dated Saturday, posted above a note from the company saying the platform would be restored after challenges were resolved.
