@mhansen, I use Google as my main search engine and never sign in. I see nothing I want missing.
I suspect a Facebook search engine will be about as successful as Google's social networks have been.
We do need an alternative to Google, but the two leading potential alternatives (FB and MS) seem to be much worse people than Google to exercise influence on the market.
