Review HN: Heykiki - Find an instructor or practice buddy for an activity 16 years ago
I like the concept. There just need to be more people using it :).
The one thing that nagged me was the popup when you click on any of the actions that kiki is doing. I was expecting it to take me to that activity's page right away so I could navigate to teach/learn/practice from there. The "Excited?" popup felt a little jarring.
