I certainly lean heavily toward the scholar, but I don't believe I've read broadly enough to take on that mantle.
The difference I tried to define between Journeyman and Scholar is that both may be equally avid readers, but a Scholar actually wants to know about the field and enjoys meta-discussions about fantasy or sf. In a sense, knowing who wrote a given book isn't that important to a Journeyman, or only enough to know what to read (or avoid) in the future. A Scholar, on the other hand, is also interested in knowing about the author because of how they fit into the context of the field as a whole.
I disagree. Every discipline has its jargon (think of the PC/laptop you're working on with bytes, bits, megabytes, routers, memory, motherboards, etc, etc), including literary scholarship -- it's the short form for conveying a wealth of information. Sages and masters would have to be familiar with this to discuss issues with one another (Wolfe, in particular, since he is a practicing academic -- sounds vaguely disreputable, doesn't it?) and Clute, in what I've read by him, seems inclined to create his own jargon as he goes along, pulling in esoteric, obscure words to denote what might be more easily understood by his audience in simpler, but probably more extensive, language.
And I would say that the "esoteric, abstract, literary-jargon" is a separate stream from actual knowledge of the field, an off-shoot if you will.
Fair 'nuff. But most scholars would have started as novices, worked up to apprentices, then journeymen. It's actually pretty easy to find yourself somewhere between such designations.
In the analogy I use above, a Journeyman may enjoy the field as one among many while for a Scholar it is a focus of study that goes beyond entertainment. So, in a sense, there is a jump between Journeyman and Scholar of commitment. For the former, sf/fantasy is one interest among many, whereas for the Scholar it is a true passion and central to their lives. This may also divide the folks that want to take their interest into the professional domain in some way, whether through blogging, review writing, story writing, etc.
