LiveJournal, only months after Six Apart sold the blogging site to Russian Web firm Sup, has resumed its tradition of corporate drama. Jason Shellen, the company's VP of product management, just announced he'd left the company. I asked him if this had anything to do with the ruckus over LiveJournal's elimination of unpaid, advertising-free accounts. "No," said Shellen, who worked at Blogger and then Google after the search giant bought the blog startup. "In social media, you have to have a thick skin." What did Shellen in was the 10-hour time difference between Moscow, where Sup is headquartered, and LiveJournal's San Francisco office.
