I'm still undecided about whether to buy it or not. I can see value in it but I'd really like more understanding of how it makes the decisions it does. I've exchanged a couple of emails with the developer and he seems a bit abrasive and snarky when questioned about the software's functionality. For example, I couldn't get a straight answer as to why the software estimated that one of my family members died in 1949 based on two pieces of data: that he was born in 1894 and resided in a particular place in 1900. By what convoluted logic does that indicate in any way that he probably died in 1949? I also notice that it also tends to tell me to search for WWII draft registrations for people who would've been in their 50s and 60s at the time. Again, not a very logical piece of advice. These are the types of things that make me hesitant about spending any money on it, especially if the revenue is not going to fund any further development. I don't even know how accurate its sources are or when the last time any update was made. I don't know. I like the idea very much but I just haven't been hit with the 'wow' factor yet.
