For the mere reason of avoiding more bad jokes and random off-topic banter, lets return to the subject, eh? HTML is the perfect form for documentation. One program will doubtlessly need to reference another, so hyperlinks are crucial, and almost every OS from 1990 on has had hyperlinked documentation; DOS had it's funny HELP program, while the Amiga had it with Amigaguide, and Mac had .... a big heavy printed manual. But their OS was crap anyways. :P But the great thing about HTML is how extensible it is. If we add some extra tags to the a element, we can make a link which points to documentation not currently on the system look it up online and retrieve it, or a document could use our lightning fast search function to find the program it's documenting, and display its version information. Note that no other format has this kind of extensibility (besides, perhaps, ODF, but we're not having a very good time just making it run as it is, so modifying it is out of the question). These are things that I think Be would do if they were still around, and having these features fits well with the BeOS philosophy.
