user-1: Right now we have piece-id, part-id, and piece-name tags.
I don't think this is a good approach. No new user is ever going to tag these right, and it's not like a question for a piece name is practically different than a question asking for a piece's element ID. And beyond that, identifications of non-pieces like stickers or entire sets should really be sharing a tag - we use the same resources to answer the question.
If no one objects, I'd like to merge all three of those into the single identification tag.

user132: We now have two separate tags for piece-information and indetification.

  identification for questions about unknown pieces or sets.
