I agree with this. For programming issues I normally use !g to search Google. I suspect Google is better for programming queries because they did a lot of indexing of newsgroups, blogs, and StackOverflow. But for everyday queries, DDG works fine (and I prefer it to Google as I don't usually want to see Google Reviews/Maps/Plus links in the top 50% of the screen area... and I don't need to see results for alternate queries on the bottom 50%).
