Without any form of communication, any and all factions would cease to exist. Lack of simple tool to organize, casual communication and internal discussion would inevitably end of most if not all non-spontaneous activity on this server. Players would be more isolated, forced to whim of random encounters of truly random quality. Not to mention it allowed me to keep in touch with people who are not on Disco anymore, or in general are hard to reach given timezones and lack of free time. Without Skype, I would likely quit disco back in mid-2009 and never come back, finding no attachment with community whatsoever. Many would follow the suit.
