My condolences to the Mattis family. James will be missed.
Like a lot of other people, I would make a point of reading and carefully considering everything that James wrote. His great sense of humour, wide range of knowledge, and surprising openmindedness were evident in all of his posts. Plus, he was just an eloquent writer.
I used to look at his web page every couple of days. It had volumes of interesting material to read and some amazing pictures to look at. James' scans were, bar none, the best on the internet: his knife pictures showed real artistry.
The thing I'll remember most about James was his overwhelming kindness, which never faltered. Actually, it was kind of weird; the guy was almost supernaturally nice.
It's hard to say goodbye, but we won't forget you, James.
