To me, GEDCOM is just another name for someone else's garbage. All too often that is exactly what they are, but even if you start with a good, well researched database, the GEDCOM will probably find some way to screw it up. Unfortunately, not all GEDCOMs are created equal, Despite the name "standard" it is anything but.
Consequently you run into problems such as I did a couple of days ago where members of my family were there, I could see them on a surname list, but I couldn't find them to merge. The reason was, the GEDCOM had used a single first name consisting of both first and middle names. I had to go in and correct the names before the merge could find them.
I have thousands of names in my database, but I know there are problems there. I'm not about to foist my problems on an unsuspecting group of amateurs who may take my word as gospel. The professionals would probably catch them, but why should I take up their time trying to weed through my errors? Besides, doing it one at a time forces me to do some much needed housekeeping, and besides, I don't need all those names here, at least not yet. I'm starting with my direct line and slowly branching out into the collateral lines as I get time. But, my data is clean, and sourced.
