I find this comment very interesting.
The vast majority of SaaS businesses that are shown/sold/started here on HN are complete mysteries to me in terms of their domain and customer base. It's rare that I see a business about which I can say "OK, I can see a need for that product." This one is yet another example: I simply can't fathom ever finding a use for this feature.
Please understand, I don't mean this in a negative sense. OP has definitely accomplished something to be proud of. It's just that my section of the industry (embedded systems) is so far removed from general web apps that I have no context for the use cases of a lot of what is introduced here.
