UPDATE: Gigaom executive editor Tom Krazit has posted new policies for accepting guest posts. The door remains open for speakers at Gigaom events and for guest authors Gigaom has previously accepted. Gigaom will begin soliciting guest posts from those it respects, Tom says. And he invites experts to pitch directly, without any PR involvement. Gigaom no longer accepts unsolicited guest-post pitches from PR agencies or corporate PR departments.
Ross Rubin is one of those guys who's been hiding in plain sight for more than two decades.
