DDG is a better search engine for developers for a number of reasons:

- Infinite scroll allows you to find information faster, even from not so notable sources

- Privacy means you can search freely and do research on issues that will probably not be found out on a civil case (patents, papers, dev articles etc).

- Bangs allow for a streamlined, faster search experience if you use certain services massively.

- Search results are very simple. No knowledge graph boxes, etc. So you can just get the content you want.

- Less (irrelevant) advertisements when you leave the search engine. You will be tagged by the content you consume and not the one you search due to privacy settings.

- Your personal data will be safe in case of a Google hack.
