Awesome. Resist the temptation to create DuckDuckMail, DuckDuckPlus, DuckDuckMaps. Stick to what makes DDG great; a simple, private, universal search engine.
I would have listed other, more toxic and/or embarrassingly unsuccessful examples, like:
- Privacy practices - Adsense/Adwords - Search personalization "features" - Docs - Buzz - Jaiku - Wave - etc...
Without Adsense, there is no Google. Everything else is just a platform for it.
One has to wonder if Google had just stuck with search, the search product would be significantly better than it is today. Instead we've got Google trying to be everything to everyone, at the cost of the integrity of those search results.
I'd like to see better integration with maps; geographic constraint and context seem to be in the natural progression of search engine growth.
