This system exists for your own good. Do not try to fight it. Understand it, instead.
Understanding your power/limitations is the first stepping stone to realize your dreams. Once you do that and internalize it, you will know how to unleash the power.
Lastly, always remember, with great power comes great responsibility.
Having said that, there are two things I noticed which I don't completely agree with.
1. The interface - the fonts, layout on the first page somehow is very unreadable. I am not sure what the motivation behind this is, but imho even a copy of hte exact google serp fonts/layout should have been good enough. The only way ddg will stand out from Google is the quality of data on your serp. There is very little incremental innovation possible from the layout that Google already has for listing a list of links and text, and it also doesnt seem to be your focus anyways.
2. I think the auto extension of search results is a bad interface choice. A pagination interface provides a clear anchoring and also for most people the first 10 results are more than enough - anything more and the information becomes too overwhelming. Again I dont think this provides any more value from the Google interface and is bad from a cognitive overload viewpoint.
Just my two cents. Best of luck on ddg.
