Another way of looking at it, independently of the inputs (time and research, in this case) is the opportunity cost of writing article on Topic A is the article on Topic B or any other potential article not written as a result. So the opportunity cost is not zero.

>A much more realistic scenario is "VFP Developer paying the bills with VFP, encouraged to focus on dotNET. As this particular developer only has 24 hours per day to be allocated between work, sleep and family, what effect will 'allocation of resource' to dotNET have? Will it affect the family? Will it affect the VFP income? Will it affect the business?" Since dotNET does not add extra hours in the day, *there* is the opportunity cost and all such developers will have that cost.
