As a search provider, DuckDuckGo tries to prevent the "gated community" syndrom:
http://dontbubble.us/
For controversial stuff, the bubble is definitely a minus. For factual queries, it just makes things easier (yes, when I type 'python' I don't mean the reptile)
I persisted and find that although the results are different, they are often just different. Once I became used to DDG it's started to seem like Google is the broken one.
It did take a while for me to switch, maybe 3 tries before it was working right.
- Queries need more grooming to get to relevant results (search for things in Dublin, get results for Ireland/Ohio/California mixed)
