I don't think I even saw this until I published the article. I don't think it was academically published, or googled well back in 2000. Nor did it match my needs for a ring buffer at the time, which was to drop stale data (I think in that algorithm, write operations fail when the buffer is full), so if I did see it, I wouldn't have payed enough attention to notice if it even had users. It's good work for sure, but that's why it didn't get mentioned.
