I have been interested in Geneology for over 20 years. Find a Grave is great in finding correct dates of birth and death in the families I am trying to trace.
It is also great to have so many volunteer photographers to go to the places so far from me that I cannot visit. When you live as I do on one Coast and have family in the Midwest and East Coast it is very hard to get to these sites. I wish my health were better - as I would love to perform volunteer work for the site - maybe in the future!
