I think you're targeting the wrong use case. Sure, some people will want to monitor their own sites for breaking changes. But I assume far more people want to monitor multiple (as in dozens, hundreds) of other websites looking for changes. Think price changes, etc.

In fact I had to implement a similar system before any of these nice technologies existed. I was working at a small company in Texas that managed your electricity bill for you in the complicated and deregulated Texas utility market. When I got there, they were manually checking ~100 different utility websites for price changes once a week. When I left, thanks to a system like this, they spent 20 minutes a day manually inputting the price change only on the plans that the system alerted them had changed.

Agreed. This is the first system that checks websites I've seen that isn't focusing on competitive intelligence. Maybe that's their idea, is that they're going to a different market. I'll be interested to see this progress, whether they maintain or pivot. However, a service like this that charges per check, and allows API access...and allows you to check multiple/unlimited pages/sites...very powerful in competitive intelligence.
