This would have been a better project, and had probably gotten a lot more traction, had it provided plugins for the big editor suites -- eclipse, visual studio, etc. As the project stood, it's neat, but at the same time, it's an impedence mismatch. You can't just annotate in your environment of choice, you have to go into a browser window to view the same code you have open in another window and see if there are any annotations. There's a place for something like it, but it needs to be a lot more intimate with how people already work in order for it to get any sort of needed traction.
