Keeping notes about the lore in your world: Tomboy

So I saw a recent discussion on writing down lore about people's worlds. A wikipedia like website is nice but some people might not like to have their world info available publicly on the internet, or just want something simpler than that. If you haven't heard of it, check out Tomboy. It's a very simple software that let's you put links in your notes and does so automatically if you write the tile of a note inside another note. It really stands out as being really simple yet very practical.
