Jeff brought this issue to my attention, and its been playing on my mind for a few hours now.
Would i write for free? I do it all the time here on the VOI, and in various other special interest blogs i maintain. Would i write for a corporate organization for free? No, i probably wouldn't. But having said that, "payment" doesn't always have to be tangible.
A very good friend of mine, a very well known published author and editor, once told me, "I get paid to write, why would i write for free (by starting a blog)?", as a response to my pestering him to start a blog of his own.
