LinkedIn, the richly funded business-networking website, is indeed laying employees off today. (No numbers available yet; if you know more details, please send them in.) But we know of at least one person who's skipping sticking around for the cuts: Reid Hoffman, the company's chairman and cofounder. He's in Japan, speaking at a conference. A convenient absence. Hoffman is described by his underlings as generous and kind, but we hear he didn't oppose the layoffs. We also notice he wasn't kind-hearted enough to cancel his trip and console his employees in person. Update: We're now told Hoffman did cancel his trip to Japan for the conference, at the last minute.
