Not true. In recent editions of Snow Crash (a fine book) Neal admits he did not coin "avatar":
After the first publication of Snow Crash, I learned that the term "avatar" has actually been in use for a number of years as part of a virtual reality system called Habitat, developed by F. Rnadall Farmer and Chip Morningstar. This system runs on Commodore 64 computers, and though it has all but died out in the U.S., is still popular in Japan. In addition to avatars, Habitat includes many of the basic features of the Metaverse as described in this book.
