On Thursday's Market Foolery, host Chris Hill and Jason Moser, Motley Fool analyst, weave through Twitter's (NYSE:TWTR) latest resignation.

Chris explains that Chief Operating Officer, Ali Rowghani, has resigned effective immediately, and says that moves such as these always perk his interest. Chris then dives deeper, and adds that Twitter will not replace Rowghani, and the stock is up as a result. Chris wants to know what's going on with all of this. Jason offers that many reasons could have created this resignation, and he adds, after reading Hatching Twitter, the social media company has had a lot of shake ups. He offers a couple of options for why Twitter may not need a COO, and explains that executive shake ups can be great headlines, but might not mean much at the end of the day. When looking at executive changes, Chris and Jason then open up about their thoughts on Disney's (NYSE:DIS) Bob Iger, and Facebook (NASDAQ:FB).
