Thanks! I agree: it definitely is a long time! The main reasons are:

1. The data from big customers was something we didn't expect. Tens of thousands of blog entries and referring domains. Measuring tractino for all of them was a no-go. It's was a usability problem (and a scalability prlbem for us).

2. We had to make a pivot. The first version wasn't as exciting as we wanted it to be. This one is, at least according to the user feedback.

3. This was mostly done as a side project. Only the past six months have been two people full time.
