But it’s a good question, especially when taken, as all such questions must be, in context.
The answer is “as many as it takes to get the job done, you DUMBFUCK.”
But to put it another way, by my comparative count, I am still trailing a DUMBFUCK INTERNET EMPRESARIO by approximately 80 total domains.
I could ask the same question: “How many fucking websites do you need, DUMBFUCK?” But I already know the answer.
We ALL know the answer to that question.
