I tried DDG a few time, but Google knew too much about me, my intent and what sites I liked.
Now I find its all ads and other google services.
Thus DDG has become perfectly serviceable now and I am very happy with it.
Although, I have an idea that the web has changed also. Web pages are different, QA sites like StackOverflow have spammed results, the rise and relentless march of commercial focused SEO, and the death of blogs and personal websites has created a real problem in search.
I somewhat wish Microsoft would sponsor DDG but not necessarily a buyout cause people will freak out. Or if they did a buyout that they would do with it as they did with Minecraft. They didnt make things worse just provided more resources to the developers.
In an ideal world someone like Apple could take DDG even but they are so unlikely to but it would further push their privacy branding. Heck DDG now owns duck.com thanks to google... So it could have a sleek marketable name.
