Ego-less genealogy?

In my dim and distant past as a computer programmer I remember being much taken with a book Ego-less Programming, or some such title.
WeRelate looks like the genealogical equivalent.

It's another collaborative tree aiming at no duplications, people linked and working on ONE version of a person/family in a wiki, same concept as Wikipedia but purpose built for genealogy, and much more easily pre-loaded with data (by gedcom).

So far I've only experimented with one small family whose research was completed (as much as any genealogy ever is) over the last few days, the Pawtucket FAIRBAIRNs from Glasgow who have sat in my database for several years without a home or further work until I stumbled upon a missing link that enabled me to link up Robert Bruce FAIRBAIRN, the banker of Roxbury, Massachusetts to Robert and Jean FAIRBAIRN, and identify Jean's maiden name as URQUHART despite the inventive spelling of the Americans over the years.  Throw in a couple of Thaddeus FAIRBAIRNs, and a Florence Nightingale FAIRBAIRN ++ and there's a little family unit to test out WeRelate with.
(if there's any direct male line FAIRBAIRN still around willing to join the FAIRBAIRN  Surname DNA project, there's still discounts going to the end of this month)

Love the validation of the submitted gedcom.
Took me a couple of goes to pass the first hurdle of date and place warnings.
Also love the ability to link to existing sources and places where appropriate.
Yet to try out the merging of submitted data with existing data, and can only see one of my RUNCIMAN clan there already to test that out on, but have to get my submitted gedcom past the next level of scrutiny first.
