Or someone who's not in a hurry, or someone who has stuff to sell that Bitcoin users are likely to buy such as electronics, especially mining hardware.
Then they have some bitcoins without having to go through an intermediary such as an exchange.
That's a sensible comment on Mr. Facts's part.
Unless it's a super focused sale like mining gear or physical bitcoins you're reducing your market by a factor of several thousand or more. You may also end up accepting much less just to make the sale after weeping with joy when someone finally expresses some interest.
I would totally sell stuff for BTC in the way I previously had access to - fixed prices and guaranteed sales from an established company. Beyond that I might attempt it for fun but would have no expectations of success.
