I know it's so common to think Aaron Swartz is special because he was a co-author of RSS when he was 14. 

But I really like one of his new side-projects, jottit.com.  Go take a look. 

It's always been so hard for ordinary people to create web sites.  This one allows you to pick a name for your site, then "claim" it, decide whether to apply a password to it, and whether other people will be allowed to edit it.  Then you're on your way, setting up your site.

This would be great as a place to share notes and links easily without using rigid templates or fancy authoring software.  It's sort of an automatic, right-away wiki.  While you're editing, you can see what your page is going to look like.  It's extremely simple and clean.
