I've been wanting to add metrics to a small side project of mine for a while and was looking at Metricfire and Mixpanel.
This announcement actually is pushing me away from Metricfire. The project I am working on now will generate less than 100 data points per day, so paying $30 a month is really high.
For someone who will take advantage of it, the $30 looks like a great plan, but when they say it is for small projects, that just seems like too much for the very small projects like mine.
