Expert opinions about the VMS

Very neatly put Diane.
However I quibble with your last assertion - a hobbyist need not be a lobbyist for any theory. Some may be - but many have no particular theory they try to thrust upon others.

That is certainly true. One can hobbyistically study the MS without settling on any solution. Though I would say that even this brings a certain amount of expertise. One can know incredibly much about the MS without being certain about anything.
