The first time I had any exposure to Om and his work was on The GigaOm Show on Revision3 (twenty years ago!). It was still a time where I thought it was wondrous that high production-value content would be distributed online for free—YouTube and friends still hadn't found themselves with "high end" content. It felt like the future of news, and it was. He was a really pleasant guy, and really far ahead of his time.
I remember these guys from the glory days of the CrankyGeeks video podcast. John C. Dvorak and Sebastian Rupley had a great double-act hosting that show.
