I think that there are pluses to using both Wikitree and Ancestry. I am adding my family in one person at a time using the research that I store and search for on Ancestry. Then using that data I am adding sources for each person in my tree and writing biographies. I was not under the impression, and I could be wrong, about taking a picture of a death certificate or census and adding it to my profiles on Wikitree. If that is a copyright problem, I'm in big trouble because I've been doing that for quite awhile.
I like the concept of Wikitree, but I do not use it for the research part, just the recording part. It takes a long time to do a good job, but I am trying to include as much as I can find and tell a story about the person. Much of my original roots web Gedcom seems to be added by another person so sometimes I hit a roadblock getting on the trusted list for someone in my direct family line from someone who barely makes an appearance on Wikitree.
