Is Snopes reliable?

Snopes, the fact checking source on the Internet, doesn’t always get it “right,” but they seem left to many conservatives because the right leaning people don’t check out stories they see on the internet and pass them along. The right makes it a cottage industry for them and keeps them in business. Facts are facts. Today I corrected a Mother Teresa quote on FB—the “Do it anyway” saying that you see everywhere on posters--for about the 10th time. It was written by Kent M. Keith in 1968. They (Snopes) cite their sources, and those can be biased—every source has some bias just by what it chooses to report or leave out. Also, keep in mind some responses called “Snopes” come from its “Forum” which is a discussion group, and not sourced. Snopes does editorialize, but so do I. There’s no reason for them not to have an opinion on the sources they find if it's positive about Trump or negative about Clinton.  There are other fact finding web sites, so you can always check more than one source (I often do), but 9 out of 10 times, Snopes is best.
