Perhaps. But I feel like Adrian has many MANY better things to do with his time then be constantly bombarded with criticism and opinions rather than running his company. I'm sure if anyone has any thoughts or questions they could respond to some of those very annoying tweets they seem to keep repeating over and over? I don't see the big deal in tweeting what you want. And I'm sure if Adrian gets enough negative feedback he will get other people to take care of it.
A CEO normally doesn't get down into the everyday trenches of trying to involve themselves in EVERY ASPECT of the business. That doesn't mean they don't keep themselves up to date as to what is going on. Far from that!
But that's why you hire people to do those other things for you. Like maybe accountants, lawyers, finance people human resource people. You know. The common mundane things you hire other people to do. Just saying.
