Um, is Snopes wrong about city cleaning crows, though? As that was the context of the original post. Which, by the way, doesn't say "Go, trust Snopes with everything; they can't be wrong!"
The context of the original post was that people should check the sources they are sharing with others, and Snopes was suggested as a source worth sharing. I disagree that Snopes is a reliable source of information or has any interest in presenting a fair and balanced narrative, because of the conflict of interest created by who / what groups fund them. Same with Politifact, or any other fact-checking organization.
