I am another that is just in shock and extremely saddened by this news. You could not have met a nicer, more genuine person than Bob. I only spoke with him briefly at the Podcast meet in Dec, but I feel like I really knew him through the podcasts. Wow, what a huge black hole there's going to be in the podcasts without him. I know he will be greatly missed by the listeners. I can't even imagine how much more he'll be missed by the rest of the team.
To Diana, Brian, and the rest of the Varely family - I am so very, very sorry for your loss.
