They promoted a widget - http://duckduckgo.com/karma.html - a little while back that when you install it on your site it uses backlink text of "new search engine" to link to their front page (rather than the page with the widget).
Sadly I don't find their actual search engine very useful at all, but the widget is excellent! It shows you your karma count / popularity on a handful of Web services including Hacker News.
If anyone needs/wants any help getting it set up (doubtful on HN), or, needs/wants other services added before use (more likely), then please let me know...
Not to co-opt any thunder, but we used the same strategy for Stormpulse.com and in doing so have become the #1 result for "storm tracker" http://is.gd/i2C3 and the #2 result (behind only the National Hurricane Center itself, and ahead of Weather Underground, et al) for "hurricane tracking" http://is.gd/i2C8.
