May be Wiki tree should stop allowing GEDCOM's, never found one on a profile that gives any info, looking up references and writting them out might take longer but you can find so many more details and is far more help to others, some people out there do not have the money to join a lot if the info sites like ancestry, so a GEDCOM ref is useless to them
More sources need to be properly written down in plain english, that will help far more people with research
