I've tried DuckduckGo, It isn't for heavy engine users. It seems like a
childrens search engine, and it has a lousy results format format.
I don't understand how Ixquick/Startpage can tap Google, yet Google goes
out of its way to crush Scroogle, which was by far the best out of what
I've found and checked on this thread.
I must be getting old, YaCy and Seeks can not replace Scroogle on its
worse day. My browser clears everything (cookies, flash) when it shuts
down. Why would I want to tie into any of these?
Clusty/Yippy fell to the dark side, after being bought they adopted a
disturbing censorship policy.
For a heave engine user, Scroogle is hard to replace, none of these is
getting it done like Scroogle; Ixquick, maybe, with a bit of
Greasemonkey, but I don't like the fact that they have Google access via
two sites while Scroogle is being forced off the net for virtually doing
the same thing.
