I love using it. It makes note-taking fast and fun and I no longer want to use anything else for personal knowledge management. Sometimes the UI is confusing and the wrong set of blocks get selected, but it's infrequent enough to be merely a minor annoyance. The advanced query feature is poorly documented and really hard to use well. It's actually a programmatic interface that sits right there among the GUI features, and one is tempted to use it expecting it to be easy. That is not at all easy.
