I would just like to dump tons of stuff into it. Scraps of thought, sketches, images, archived web pages, pdfs etc... then have it organise itself, finding links and connections between things, perhaps with some way of shaping and guiding it. I just don't have the patience to tag things or organise things into a hierarchy. I inevitably end up with a huge blob of 'uncategorised' stuff.

I wouldn't mind if the algorithm for making connections made some mistakes - the important thing would be helping you connect things together in novel and unexpected ways, based on your curated collection of stuff. Serendipity is super important.
