None; sounds like a good change for Twitter and probably the best thing that happened to their board in quite some time. I did laugh out loud when I heard about this yesterday. There is a more than a bit of history between Elon Musk and his many detractors and a lot of that involves Twitter. So, Elon Musk buying himself a seat on the board is more than a bit ironic.

The man definitely seems to float from one controversy to another and quite a few of those controversies seem to involve Twitter. Buying a big share in Twitter is kind of a ballsy thing to do. But why not? Might I suggest shorting the stock if you disagree ;-).
