Thanks! One more thing, right after hitting reply, I realized the numbers you saw sounded too high. So I checked out our pricing page and it turns out we had a regression in the estimator. 50 metrics reported every 60 seconds costs $4.46, not $26.78. For the $26.78 you can push 300 metrics every 60 seconds. Just pushed out a fix and it shows the correct values now, so this exchange was really helpful!
I myself was skeptical when reading OPs numbers, but if I can get reliable metrics like that for just $4.46 a month I might even consider using your service! You should definitely edit your post above to reflect that the price was too high for the numbers quoted, as maybe not everyone will read this far in the thread to discover it.
Wow, that makes a HUGE difference in price. Now it makes a lot more sense and leaves me wondering about your QA practices. Just pulling your chain. ;-)
Anyway, the fact that you are responding here and being active would definitely make me feel like your company would be the first to check out. This is similar to how I feel about WePay as well. Their ceo and engineers read HN and respond to comments. It is the dawn of a new era of access and support.
