Andy Wingo, Geiser's first user, has been a continuous source of encouragement and suggestions, and keeps improving Guile and heeding my feature requests. Eduardo Cavazos' contagious enthusiasm has helped in many ways to keep Geiser alive, and he's become its best evangelist in R6RS circles. Eli Barzilay took the time to play with an early beta and make many valuable suggestions, besides answering all my 'how do you in PLT' questions. Matthew Flatt, Robby Findler and the rest of the PLT team did not only answer my inquiries, but provided almost instant fixes to the few issues i found. Thanks also to the PLT and Guile communities, for showing me that Geiser was not only possible, but a pleasure to hack on. Karl Berry happily jeopardized GNU's prestige by reviewing and accepting Geiser as a GNU official package.
