Elon Musk, the CEO of e-automotive company Tesla, has sent a Tweet seeming to criticize the US Security and Exchange Commission. It was posted shortly after this body's decision to fine Tesla and strip Musk of his position on its board. The tweet may be linked to a subsequent 7% drop in the company's share price.

I've only followed some of these stories loosely, but it seems like the guy is allowing himself to get caught up in stuff & losing perspective.
I really don't understand why people with celeb status bother with twitter at all. It's just not worth the hassle
