The site's interface is just incredibly pleasant compared to Google.com. I really hope the author sticks with it. Unfortunately I'm not sure it's usable right now, searching "group theory Wikipedia" never brings up a Wikipedia page (although maybe I should just be directly searching Wikipedia if that's what I wanted).

DuckDuckGo's approach of !bang searches, making duckduckgo the place[1] I go when I want to search another site, is really useful.

[1] It's my default search engine in Chrome, so I use bang searching in the address bar.

Same here. The problem is that I find myself using `!g` way too often... I guess I'm not used to the DDG results page.

ddg is my primary search engine, it takes time but you get use to it. If what you are looking for is mostly on HN, SO or wikipedia it works quite well.
