OP here. It depends what you use it for. You do want the tags if you intend to generate data. Let's say you prompt an LLM to go tweet on your behalf for a week, having the ability to:

- Fetch a list of my unique tags to get a sense of my topics of interests

- Have the AI dig into those specific niches to see what people have been discussing lately

- Craft a few random tweets that are topic-relevant and present them to me to curate

Is very powerful workflow that is hard to deliver on without the class labels.
