"All this stuff was done via FTP but the web has put a really nice user interface on it"

In this quote, Jon Postel is referring to the evolution of innovation and how it has actually altered the way we gain access to and share details. He discusses FTP, which represents File Transfer Protocol, as an approach of transferring files online. In the past, this was the main way of sharing files, but with the introduction of the web, a more easy to use interface has been created. This means that rather of using complex commands and codes, we can now quickly browse and interact with the web through a visual user interface. Postel is highlighting the benefit and accessibility that the web has actually given the as soon as complicated process of file sharing.
