Unfortunately the blog you have quoted is incorrect. Familysearch.org refer to the Guild of One-Name Studies in their Wiki, you can't search anything on the GOONS website from familysearch, you can only carry out limited searches on the GOONS website, unless you are a member (you can be a member without registering a name).
To answer Dave Dardinger's question, the GOONS have very stringent research and sourcing requirements; the aim being that each name registrant becomes the world expert on their paticular registered name(s); mine are Hawkesford and Beamiss.
Ultimately each name will have a Guild supported web site, which is accessible to the public. Any enquiry from the public, to a name registrant, must be answered in a timely fashion. A very good example of a Guild registered one-name study website is that managed by Debbie Kennett, for her Cruwys name study (which can be found here: http://one-name.org/name_profile/cruwys/
). Debbie also operates a brilliant blog 'Cruwys News', which can be found here: http://cruwys.blogspot.fr/
); she is also the author of 'The Surnames Handbook: A Guide To Family Name Research In The 21St Century', a very good read with exceptional web links.
