We call it jokingly the Mountain Viable Product because it took 14 years. I wanted to build a platform that I enjoy using, so it took a while. But hey, we are here! :P
I did have a few users for many years and I was testing with random strangers I caught on the street (which turned out to be lots of fun), so at least I wasn't completely in the dark.
I hope to get more feedback & users soon.
