Square seems to be aware of some of the risks it is taking by going public. Now that it's more accountable for turning around a profit and showing growth to investors, it will need to justify more of its actions and products. And the company's co-founder and CEO, Jack Dorsey, was also just named CEO of Twitter (for the second time, following his original ouster from Twitter in 2008). Square's S-1 paperwork explicitly says "Jack Dorsey, our co-founder, President, and Chief Executive Officer, also serves as Chief Executive Officer of Twitter. This may at times adversely affect his ability to devote time, attention, and effort to Square."
