At 4:00 PM EST on 3/3, you can ask Valve's fearless leader anything.
Update: One hour later, it seems the AMA is a no-go. It appears that Newell didn't follow the proper format and Reddit appears to be deleting all questions. Now we'll never find out when Half-Life 3 is coming out!
Original story: Gabe Newell, co-founder of the Valve Corporation, is doing an Ask Me Anything on Reddit in just a few minutes. That's 4:00 PM EST, 1:00 PM Pacific time for you West Coasters.
It's probably just a coincidence that today's date is 3/3, right?
We'll update this post if any news should happen to break during the AMA. You can tune in here.
