Are you arguing against niche markets? Or people finding a calling and
pursuing it, and making a successful living, in spite of a smaller
market for their particular product or service?
By that argument, you could say all computer books are pointless. If
these authors focused on romances, horror fiction, and biographies,
the market share would grow tremendously!
Or do you feel that someone was denying that the PC market (for books
and most everything else) is larger?
