Some interviews, memoirs, etc., in TUGboat and elsewhere

The TeX Community Blog is doing its own interview series. Originally Paulo Cereda did the interviews, but later others in the community joined Paulo during the interview sessions. They have a dedicated chatroom for interviewing their members; anyone can visit the chatroom and submit questions to the interviewee; and Paulo serves in an editorial role. Other interviews, memoirs, etc.
