Portal 2 co-writer Jay Pinkerton's back at Valve
Valve veteran Jay Pinkerton has returned to the developer a year after he left the company.
Pinkerton left last June, following other high profile departures from Erik Wolpaw, Chet Faliszek, and DOTA 2 writer Marc Laidlaw.
Now, thanks to eagle-eyed Redditor OWLverlord (via PC Gamer), it seems Pinkerton is back on Valve's staff page, listed under the "Other Experts" category.
