The FAQs link directly to http://www.livejournal.com/developer/styles.bml, which is reasonable--it's introductory. However, that page is really written to be gotten to from http://www.livejournal.com/developer/, and it's not obvious that "back to the developer area" will get a new user of styles somewhere they particularly want to be. Also, the description of variables and properties on styles.bml doesn't obviously lead anywhere. Might I suggest an addition to styles.bml, at the end of the Variables and Properties section, along the lines of "For more detail on variables and properties, check the Developer Area." ?
This is in response to a couple user requests where the user has clearly tried to read all the FAQs but couldn't find his or her way to the nuts-and-bolts section.
