Seeing all those SRFI's listed, etc, on that page (63 of them), is astounding. How long would I have to work with scheme to get to comprehend what each represents without looking them up Captain Wimby's Bird Atlas of Nomenclature? What percentage of the people who take the time to read that page, for example, if they are trying to learn if Chez Scheme might fit their needs for a language implementation, are going to get a good idea about anything by scrutinizing that list? Isn't that like a bookstore filling its advertising with a list of ISBNs? I have tried to do some stuff with scheme at times in years past, and when I saw such lists galore with no plain-language information attached while trying figure out which tool to grab, it gave me some idea that the scheme community was a somewhat isolated ethnocentric culture of its own.
