Option one : Who is still using boring directory nowadays? Keywords SE is "in" and directory is "out"
Option two : hhummm... This is not new. But do you really expect a large number of visit? Who are you targetting (local, regional or national level but not international level). And the DNS is not the best choice for this option.
If you are not professionnal, then I would go for the option 3, just for you to have fun (professionnal are used to create boring website for customers). Browse the web, and try to make something new (this is the hardest part), cool and fun. simplelinks.net sounds like a very simple and basic website (<15Kb per page), it should go fast and it should a place were people can have their say and drop/search for links.
