I've encountered a number of profiles that cite only "geni.com" as a source. No hint as to a URL or the nature of the cited content. Considering that Geni is full of misinformation, I see little value in going to Geni and trying to guess what the contributor was trying to cite, merely so that I can supply a link. I probably won't delete the indication that the profile came from Geni.com, as that tidbit could be useful to somebody, but I'm not going to go to the trouble of finding a specific link. Why not look for a real source instead?
