If you're Williams it probably doesn't matter. As long as people keeping sending an exorbitant amount of Tweets, the Twitter co-founder can continue to cash in.
And on Monday he did just that. Business Insider reports that Williams sold $100 million worth of his personal Twitter stock and he is still the company's largest shareholder.
Williams was not in any dire need of cash -- as far as one can tell. He sold his last venture, Blogger, to Google for millions back in 2003.
