listing lists lazily

Here's the thing, right? I'm lazy... in a good way! I want to be able to list lists and update lists in my blog template, without actually going in and editing the html everytime I want to do that... anyone got any suggestions to anything *free* that i could use? even if i have to log into a site to update the list, and have it automatically update on my site... hopefully someone out there has a solution...

examples of lists i want to be able to list and update:
- links
- movies (what i'm watching / have watched)
- music (what i'm listening to)
- books (what i'm reading)
- wish list
- the possibilities are endless...
