I'm a little unclear on the timeline here, but Mullenweg just got back from Burning Man. I suspect that's related to both the content of the post and the board's timing.
Matt is Automattic's CEO.... I see what you're doing... ;)
We/I want to build useful things. This is a distraction. I believe Automattic is a net benefit for the web and look forward to having more focus to continue delivering on that. Internally, were focused on that.
Sounds like you've never worked for a CEO with "ideas." One time a CEO made the whole R&D team switch to "aspect oriented programming" because he had read a blog post. Another time we had to switch to C# because he had heard it wad better than Java.
I worked for a company with co-CEOs. The ideas CEO left and the company tanked. I think there's a right way to have an ideas CEO but maybe a balance helps keep them from switching everybody to C# on a whim. A CEO without ideas seems like a recipe for at best stagnation and at worse just fleecing the company of value and taking a golden parachute.
