I just noticed an obituary on a genealogy blog copied and pasted from either Legacy.com or from the electronic edition of a newspaper which published the same version. The blogger did not include a link to the original location, nor did she include a source citation for where she obtained the item. The blogger is not giving credit where credit is due and is, therefore, guilty of plagiarism. As often as we hear the three words, "Cite your sources," in genealogical circles, you would think that the proper documentation would have been automatic.
I also just noticed a post by another genealogist who wishes that she had not shared information with another genealogical researcher. Why? Because that person had posted the information and photos shared without proper attribution. I wish I had a dollar for every time I've heard this sentiment echoed. I'd be a rich person. CITE YOUR SOURCES, people, CITE YOUR SOURCES.
