Having a founder and product visionary (Jack) in the driver's seat at Twitter is absolutely the right move. Sure, Jack has his quirks, and seems a little bit crazy and minimalistic, but that's exactly what makes him the right person for the job.
Twitter is executing on its vision now just fine, but that's just the problem: There hasn't been any vision left in the company. No truly big moves have been made, and the product has remained almost entirely the same (with the exception of fonts and colors constantly moving around the screen and a lot more ads).
