Why do they use www.duck.co as their development url and www.duckduckgo.com as their search engine name?
The latter is just way too long to type. Especially for casual users who has google set at their main search engine. Compare URL lengths:
duckduckgo.com 14 (10+4)
google.com 10 (6+4)
yahoo.com 9 (5+4)
yandex.ru 9 (6+3)
bing.com 8 (4+4)
baidu.cn 8 (5+3)
I really want to like duckduckgo, but the name is really not well chosen. Even google (with a relatively long name) at least have two repeating characters.
