Firstly, LDS tries to portray itself as the modern day pious scribes toiling in the catacombs of history all in a selfless effort to keep accurate records... THAT is complete BS. They did have the best bastion of information and I will gladly give them kudos for that.
But oh man these people didn't just ". Drop the veil..." they dropped it after they used it for a tissue, tripped over it and curb-stomped it to hell... they have just completely blown it! Whoever came up with this genius plan should be let go and fined for having no idea what they were doing messing around in this website. This used to be a user-friendly, relaxing, delightful website full of easy to retrieve and store family history info. Now, it is a "re-designed" "improved" "prettier?" nightmare of aggravation and tail-chasing.
Well hey! Now they are just like Ancestry.com and every cheap, ineffective website like them. Ancestry.com, the original, jerk-you-around-for-hours until you are utterly frustrated and feeling, well, completely jerked around having accomplished nothing except many many many many many profitable clicks for the company and you are left with nothing.
I called FamilySearch.com and the nice person wanted to hold my hand to help me "clear your cookies"... puhleeeese don't patronize me. You have destroyed the best global genealogy site which used to be good for an afternoon of family enjoyment and a useful, efficient tool for genealogists and turned it into an incredibly annoying waste of time.
They have actually lost information and they have messed up the ability to upload saved information (that you spent precious time finding and saving). You put in date parameters and "exact spellings" only to have zillions of dates completely out of the range you put in and unbelieveable misspellings and inaccurate information! It is positively unbelieveable. Even the error messages are ridiculous and make no sense: "We can't upload your file because we can only handle twice the size of your file"... quite literally the message---want to leave feedback? Well it says, "Looks like your new here... sign up or login to leave feedback..." Um, I am logged it but since they have a new format, maybe I should try to sign up. Nope. When you hit "Sign up" or "Login", you get a big, goofy, annoying "Whoops! We cannot auto-connect because...". Seriously, this has to go down as the biggest, self-inflicted snafu in website history. Things were just going too perfectly for too many years... can't have THAT!
Now, let's see if they can admit this is a collossal disaster and revert to the former recipe for success or will they insist that everyone LOVES it and continue laboring under the delusion that everything is swell when in reality, not only have they made a GRAVE ERROR in judgement but whoever is responsible for this was in no way qualified to alter one thing as evidenced by the end product. What a SHAME.

Before you begin with FamilySearch.org please first understand that it is a COLLABORATIVE website. Aside from living relatives, EVERYTHING else is shared and subject to communal editing. When I read through the critical or negative reviews I came to the conclusion that they were written by people who do not really get what a collaborative website looks like. There is no "your" tree! There's only one single, communal tree. It is very similar to WikiTree and in many respects both websites have a similar mandate and a similar philosophy.

Now, for a review of the site itself.

The interface is simple yet remarkably powerful. It has a wealth of well-chosen data sources--in some cases missing from the commercial paywall sites. And, the search algorithms, once you figure them out, are also extraordinarily powerful. Depending on the part of the world you're researching FamilySearch may be the perfect research choice--for Dutch genealogy, for example, I can't see a better website.

I've been using it for four months now and I have not found any software or any website that is anywhere near as powerful as FamilySearch when it comes to building a family tree. If FamilySearch.org were to be spun off as a privately controlled family tree website it would bankrupt MyHeritage and maybe Ancestry--the interface is second to none and it's trivially easy to document your work. But, a lot of people don't like its collaborative nature.

Much of my work happens in the Netherlands and the coverage of records is stunning.

In the right parts of the Netherlands and with a bit of luck, it's possible to use FamilySearch.org to create a properly sourced, RELIABLE tree for an individual dating back five to six generations with only a few hours of work. YES, six generations in a few hours of work! Because I'm working on DNA matches with Dutch relatives I've now created full ancestral trees to prove a connection--and more than a few times I've managed to replicate an entire tree in an hour that almost always matches the family tree that the match had for their ancestors (sometimes mine are more complete, thanks to the search algorithms for FamilySearch.org).

As for conflicts with others--I've only run into two individuals who have conflicting views to mine. In one case it related to a differential interpretation of the facts, and I think our amicable solution (to document the different and equally valid interpretations of the documentary record) was satisfactory. In another it was someone who took "ownership" over an ancestral branch that lacked documentation. Since it was an undocumented branch I left their fantasy alone--genealogy without documentation is fantasy and should be ignored unless it interferes with the proper functioning of a site.

That said, in a few cases I've had auDNA hints that suggest that some ancient connections (early 1700's or even late 1600's) may indeed be correct. I'm not prepared to accept those connections as valid without a lot more research but it's indeed quite interesting.

The one thing I've always wondered about is the affiliation with a church. So far I've not seen indications that's a problem. What I'd be more worried about is that it's a website hosted in the US and the US has extraordinarily weak privacy laws.

PS It's too funny. This is only "second" review at this website. It seems that I reviewed FamilySearch in December as well. I can't see what I said the first time around but this one is now informed by many more months of experience.
