We use it to organize data within our Hackerspace and love it. It's both hacker-friendly and usable for the regular users and has a couple nice features, e.g. presentation mode. The only two issues I can think of are:

1. It's easy to get lost in the index view if you have a lot of notes,

2. It crashed once when we shared a lot of images.

Anyway, overall it's an amazing tool!
