It looks interesting. There are two features that would make me really excited (could be that I just didn't find them in the few minutes I looked for them). The first is the ability to link notes directly to each other and then view the notes in a graph view, mind-map style. I see the graph view for tags, but nothing for viewing notes in a graph. The second is a mobile app, cause I do most of my note-taking on my phone. The web interface is useable on my phone, but not really ideal, as many of the controls are too small for my finger to reliably hit. I don't know how much I line up with the target audience here, so there could be good reasons that those aren't planned or prioritized.
