I've been using it for a week, I like it.
Health food features: (features that are generally good for you but which you don't notice specifically at each use)
- Access via https, if you want.
- Logs deleted quickly
- Less data about you collected by Google.
Note: For Firefox, if you want to put the https version of DDG in your search box list, use the Add to Firefox link on the DDG page, rather than "Add Duck Duck Go" in Firefox's search box dropdown.
Immediately tasty features:
- Clean results page.
- Clean results page URL.
- (Some Linux distros dirty it up in Firefox.)
- If not many results, there's a link to the equivalent Google search.
- This is so polite and helpful it's classy.
- !Bang notation for alternate search engines.
The !Bang notation is enough by itself to use DDG as your default search box entry. I have alternate search engines in my Firefox search box, but I don't use them much because even "alt-downarrow ..." is just inconvenient enough to dissuade me from using it; then you have to switch it back. "!w" at the front of your query to signal a Wikipedia search is a pleasure.

Well done.
