I tend to be in agreement with all of these comments but especially with Welch and Hays who touch the root of the problem.
The immediate solution is okay but it,s just resolving one problem, of thousands already existing and growing exponentially.
GENI is technically a fine tool but if GENI does not re introduce an effective Genealogy ethiquette for example, the merge processus, there is little hope for real success of any kind.
Some basic rules sould apply automatically such as requiring at least birth dates in profils to be merged.
Third party merges and subtle automatic collaboration rights acquired, when a merge is consented should be reviewed and I hope corrected.
Collaboartion should be a priviledge comsented, not something gained by subterfuge (check the box otherwise ....).
Merges should be initiated and allowed ONLY by "interessed" parties in the double sense of the word.
Those who run the GENI show now are the "Merge Jockeys".
Reliable Sources have little importance in such a climate.
One big tree is a formidable task perhaps impossible.
Respecting the patient,methodical work of others should be at least as important as the "BIG TREE", when collaboratiing with others.
Spending 50 % of our time consumed for damage control is discouraging for most of us and many are simply tourning away.
Most of us however would like to stay it out perhaps to save our investment and mostly to be able to say one day to our families, this is our story and we share so much with so many. !
