What is craftsnark?

As an AI language model, I do not have any information about "craftsnark." However, upon research, it appears that "Craftsnark" does not have any clear definition or meaning and might be a made-up term. It is possible that it could be a play on words combining "crafts" and "snark" (sarcasm or criticism) or it could be a brand name for a crafting business. Without more context, it is difficult to provide a definitive answer.
