Kinda missed this under the radar until Jeri mentioned this.
He's a pretty cool guy and seems like a good match for what's being worked on at valve.
Mightyohm talks about valve during the amp hour here:
around 24 mins in, Jeff talks about how challenging it is to get into valve. I thought when Garry interviewed with valve he just had a bad day, but now that I see it Garry probably did just fine.
The amp hour episode does demistify some questions I've seen on facepunch people have asked, so the EE people might take a gander at this.
