Hm, well, while it looks good, it suffers from the total lack of a search function... if you want simple but highly functional, I'd go with TiddlyWiki, myself. But much will depend on the quantities of data you're handling. So DEVONthink and, indeed, Scrivener, offer interesting alternatives for handling very large amounts of data efficiently.
