Key findings include:
- AI dominance: Posts related to artificial intelligence have surged, reflecting broader industry investment and public interest.
- DIY hardware revival: Maker‑focused content is gaining traction, indicating a growing enthusiasm for hands‑on projects.
- Year‑over‑year performance: While 2023 and 2024 showed steady engagement, 2025 experienced a notable dip, suggesting market saturation or shifting user priorities.
