Developers and tech enthusiasts struggle to track what's trending across different communities and platforms. A tool that aggregates and visualizes these trends would help them spot emerging topics.
Build a web app that pulls data from popular forums, applies topic modeling, and displays trends on an interactive map or heatmap.
Charge a monthly subscription to analysts, investors, and tech enthusiasts who need to stay ahead of trends.
Start with a simple visualization of Hacker News data, then expand to other forums.
The main risk is ensuring reliable data sources and maintaining accuracy as the platform scales.
