From the Delicious blog, I’ve learned that you can now apply a Creative Commons license to your del.ici.ous feed (it's under settings → license). Since I wanted to encourage other people to make use of my feed, I set mine to a Creative Commons Attribution license. In short, that means that you needs to give me credit, but that’s about it.
In case you’re new to Del.icio.us, it’s a social bookmarking site. You can add bookmarks to your de.lici.ous page, each with a set of “tags” (which are a bit like keywords). Then, you can look up sites based on a text search or the tags which you’ve used. And, that's just the start. In a previous post about del.icio.us, I go over several other features of the site.
