I find it hard to find communities for my ever-changing niche interests.

I’m working on community discussion boards which exist at the intersection of interests.

Eg. Mountain Biking/New Zealand, Propulsion/Submarine, Machine Learning/Aquaponics/Tomato, etc.

The search terms for interests are supplied from Wikipedia articles which avoids duplicate interests and allows for any level of granularity.

I find that key word functionality in search engines has degraded to the point that finding good content for niche interests is difficult. I’m hoping with this system I can view historical (and current) discussions around my many niche interest combos.

I’ve got the foundation done, I just need some feedback/advice on whether I’m reinventing the wheel here, or if others share this problem?
