So you're playing dumb? Do you want to see if there are enough others who are playing dumb? Of course you know engagement can't be bought. You can pretend, but nobody believes it anyway because nobody buys it. What you see on your blog is not engagement. Insofar as you don't expect intelligent answers to your questions, the engagement is less than a joke. Of course, you can still say that it can be bought, by someone who can pay you.
But this person would not get your commitment, but a kind of bored cynicism. Or artificially generated excitement. Take your pick. The supposedly smart statement "You give me money, I do shit for you", does not even represent the precursor of engagement. Rather, it reflects an attitude that provides the basis for non-engagement. Those who chum up to you and make it look like an engagement are playing dumb and want to be paid by you for their non-engagement. My conclusion is this: "You buy non-engagement and what you consequently get is non-engagement." Is that something you want?
Or what do you mean anyway by "engagement"?
