He always struck me as a well-read, but unimpressive 14 year old.
That's not the impression I got, but even if it's true, I'd welcome such members over the usual spammers any time!
My first impression was that nullius was a genius "Bitcoiner", I enjoyed his techincal posts and I did learn some great stuff from him, somewhere down the line he made a 180 degree change in the content he provides to the forum, he went from that tech-savvy member to a repuation-addicted member, he got himself involved in all the mess of forum trust issues. So if he ever comes back, I hope he goes to back to development & technical discussion, the place where performs best.
