- The site is NOT mobile friendly (it wasn't a consideration in 2007), and the specific segment of the population that appeared to be the majority of users (people who had access to computers but didn't own graphing calculators) now have phones and look to their phones for graphing calculator functionality
- There are competitors with better UIs (http://desmos.com/) that sprung up later and seemed to have sweeped up a bunch of users from mine. Mine was, to my knowledge, the first web-based graphing calculator that you could click and drag the graph around with the mouse, and zoom with the scroll wheel.
- There are lots of new features in web browsers that could make it faster, snappier, and also support 3D graphing, which was a popular feature request
- I could base it off React and also release both mobile apps as well as a webapp, since people today seem to prefer native apps to webapps
- It looks outdated compared to modern graphing apps available for iOS and Android
That said, no motivation to do the above unless I had a guaranteed payout. Making graphing calculators isn't what I want to be spending my time on now considering the site is <1% of my income now. Back when I was a grad student, back when it had a lot more users, it was >30% of my total income. If someone gave me 30% of my income now to modernize its UI, I'd do it.
