Yeah, I'm using Iris since it was the first one that was sort of functional, but it looks like it's being overtaken by others gradually. Too bad.

I was a little harsh early on (unjustly so), and I know making a web app with tons of asynchronous data flying around is a big challenge to do correctly.

As much as I dislike the entire Javascript ecosystem, from language to tooling to community, it's a testament to modern web development that it's possible for one person to make this kind of app as a one-man show. Hopefully he's able to stay in the game and keep making it better.
