Yeah, agreed that some of the features the author cites sound great...but, then i wondered similar to you that even if i *only* bring up some random notes, it would still be better than what i have now (which is nothing!). I imagine bringing back random notes helps for a few reasons:

* Can prune old/outdated/now-irrelevant stuff

* Can learn/re-learn stuff

* Can consider re-writing/updating some the re-surfaced note, maybe because i have better understanding of some concept nowadays as compared to when i originally wrote some note

* Maybe some old ideas spark thoughts that generate new idea(s)

...etc., etc., etc.

You have inspired me to craft a little script to bring up random notes from my collection. Thanks! :-)
