Personally, I've found it to be anything but a "procrastination-forming pseudo-notetaking program."
I say Procrastination-forming because in my experience with these kind of tools you end up spending more time formatting and aesthetic-izing your stuff than actually doing notetaking. Look at the demo video on the main homepage and one thing they emphasize is on putting small icons beside the bubbles and having neat background colors.
I say Pseudo-notetaking becuase this tool is actually more geared towards structure than creation. Your video for instance doesn't show anything related to my idea of notetaking. Notetaking means you are writing down quotations or details upon ideas that you're listening or reading about because you wish to remember them or study later. Notetaking, in my mind, is not limited to linking Ayn Rand as an author and 1902 as a birth year. There's no depth to anything.
In the end if you say it works for you then go for it. But I'm just saying that if it's really notetaking you're interested in then I really don't think this is the program to use.
Aesthetics are a factor, but the icons, for example, are generated automatically by favicons when you link to a webpage. No procrastination involved!
As an example, if you're reading a dystopian novel you could create a node for "Dystopias" under æTypes of Literature" that has "Brave New World" and "1984: as sub-nodes with notes for each book in their node. Those could link to nodes for the authors with maybe writing advice from Orwell and/or Huxley. Then you could link from them to a node about a current event or article that seems to fulfill their somber predictions... etc.
The same "Brain" could also have notes on topics as disparate as programming languages, biology or travel, all in one searchable, non-siloed place. You can create connections between nodes at will.
I've used it for several years now and can't recommend it highly enough. I wouldn't, however, mind seeing competition in the area as they seem to be the only company that makes software like this.
