I struggled to get people to use the site last time around. And I couldn't get any feedback either. I felt like I was just shouting into the void and things eventually stalled.
I'm now putting more work in having pivoted the idea from an analytics platform (I guess anglers don't care too much about the data) into a social platform where people can share photos of their catches and you can see your friends sessions.
I'm also adding more of a competition focus. This month's is a simple one designed to get people to upload photos and try out the new features.
