I suspect that this scenario is played out again and again across the world. Genealogists spend years of their lives doing research but often failed to provide for the preservation of the records. Today we have a rather simple way of preserving the vast majority of the research done by all the genealogists in the world. That information can be placed online in appropriate websites.
In this regard I came across a presentation made by Israel Pickholtz. Unfortunately, the text of the presentation does not identify either the date or the place, but the information presented reaffirms the need to preserve genealogical information. The presentation relates an experience where a relative of the presenter died and all of his research was lost or unavailable. The presenter suggests using Geni.com as a repository for permanently storing information. I certainly agree with this opinion. This is especially true since Geni.com was purchased by MyHeritage.com. This acquisition makes the survival of both databases more secure. An alternative online website would be FamilySearch.org's Family Tree. Granted, Family Tree is still in the development stage but it shows much promise in becoming an extremely valuable place to preserve genealogical data.
Although, there are a substantial number of negative factors about online family trees, it is important to understand that they are a vital repository for preserving and securing genealogical data that would otherwise be lost. This is not true of every online family tree, but the presentation cited above and my own experience clearly indicate that there are places online where genealogical information can be reliably preserved.
