I'd assumed that at first but your statement about how absolutely every rich site should be using MixPanel hinted at something so unreasonable that it made me "take you down a peg in my estimation".

I don't trust Google that much, I just trust the others far less — there are degrees of infinitesimals! Besides, an untargeted score on GA would be such a hueg firehose that y'all would be way down the list of people to sift through data for much less prewrite an exploit for.

Even you writing your own code to ship specifically detuned events to MixPanel makes me somewhat uneasy.
