I was in TEST the entire time I played Eve (from day 1 of Dreddit until about a year later). I don't think I ever spoke to him, but had small indirect interactions - being in the same system during a siege, listening to him on voice chat, buying items from him in VFK.
He was a legend, and it's hard to overstate the impact he had on the game. His actions and words could and did affect the fates of literally tens of thousands of Eve players (really, most of the population). He was a large part of the reason Eve has the rich, complex, and unique metagame it has. It may sound silly... but for everyone who played, these things mattered.
