I remember not too long ago, he made a post in which he referred to the fact that he'd managed to successfully battle his illness a few times. I always admired how he wasn't afraid to bring it up from time to time and how strong he seemed.
I didn't have very many direct interactions with him, but I always enjoyed reading his posts. I remember thinking that he must have had a wicked sense of humour IRL, and that he would be the kind of person I would have enjoyed sitting down and having a beer with.
My condolences to his family, and to everyone who knew him.
