For a random individual plucked out of general population, you would be correct. Three is hardly anything. However, for individuals that effectively determine what actual average is to a population ( by shaping tech that shapes said population at the very least ), it does not seem hasty. It may be a proxy, but it is not hasty.

It seems wise to be wary of a salesman who won’t let his family use the product they sell. This seems very common in the modern tech industry.

If I were a billionaire I'd have servants who would use social media for my servants, to be fair.

Why have social media when you can have Jeeves "do it" for you?

Unless you’re a public figure who is posting as part of your “brand”… why use it at all at that point?
