For me, when it was all email at previous jobs, I had trouble distinguishing signal from noise. And it's pretty easy to ignore if you're really busy. Early on you have it go to your inbox, then it becomes too much and you start filing it into a folder, then you create a rule to automatically file it, then it's all too easy to stop checking it unless something blows up.
I also think anyone who goes for a solution like this gets tired of the feature creep distraction. Implement a library in every language you use, now it emails too much because we're getting more traffic and there's no de-duplication so rig up something to do that, there's a bug in the de-duplication code and now it is in an infinite loop because it's reporting on itself, and by the way, quickly find all users affected by this front-end form bug so we can email them a coupon and apology.
I think you're blowing the whole thing out of proportion. When there is an error on my site, I fix it. If there is a bunch of duplicates, I fix it faster since it shows me that something is broken.
My product is just a website. I don't need to implement this in 'every language' that I use. I have the backend email me when there is a problem and I have the frontend email me when there is a problem. Since I fix the problems quickly and I don't write crap code all the time, I generally don't have a lot of problems.
Problem, what problem?
By contrast the $25 plan on Airbrake[1] is 15/min and the $29 plan on Coalmine[2] is 20/min. The free plans for both are about 1-2 per minute. (Disclaimer: I work on Coalmine)
But it does sound like a good service. Nice that there's some competition in this space finally--that's great for everyone. :-)
