In a shout out to game creators big and small, Valve Software has announced the operation of its own game developer conference. Steam Developer Days will be a two day event to be hosted in Seattle on the weekend of January 15-16 2014, that encourages developers to attend and share their "design and industry expertise" in a "relaxed, off the record environment".
Off the record unfortunately means that press types aren't welcome, presumably so fellow developers can mingle and share ideas without fear of media scrutiny of their current projects, however the event will be host to a schedule of lectures by industry veterans that will be recorded for posterity, so perhaps there's potential for some of those to be made public available after the fact.
Topics already on the agenda are virtual reality, Linux and OpenGL, and user-generated content, and attendees will "have direct access" to the Steam Team, and have the chance to "test-drive and provide feedback on" Steam OS, Steam Machines and the Steam Controller.
