I like Bing. I hate how Google moves from the home page to the initial results page after I start typing. I like my windows to stay in one place until I click something.
I find Bing to be slightly inferior to Google, but only on about 1% of my searches.
Plus, I like the pretty pictures.
I asked it a stoopid question to see how well it works:
how many murderers in a given population
Answer: Enough.
It seems well-programmed. 
You can turn that behavior off, you know…I think. Unless they changed it recently.
In a sense I use Google every day, as Chrome is my browser for everything but the Dope and typing in the Chrome address bar is enabling a Google search.
That said, I’m just as likely to use DuckDuckGo these days.
When Bing came out, the fella tried a side by side comparison. He picked a random thing (I forget what) and searched each. A couple of times. (Different topics)
According to him, Google blew Bing out of the water. He’s much more analytical than I, and I trust his opinion.
I give other vote for Google.
I use Yahoo sometimes but not often
Google, and when their nannying my search terms pisses me off too much, duckduckgo.com
I tried it when it first came out and I thought it sucked.
So I just tried it again, “pick module optimization” and then “order fulfillment optimization” - nothing that it recognized, whereas google brings up various articles/papers about it.
What kinds of topics do you have success with?
It can do lots of things but you can use it like an almanac. Type in the name of a small town or a college for example. It gives you detailed information on it that easier to read than a Wikipedia article or a series of Google returns.
Bing (the default search engine on some work computers) is a pile of crap.
Sometimes I use it to search for “Google”, which probably fries its mini-brain.
“Nannying” isn’t going far enough. I was searching for a specific phrase yesterday, so I put it in quotes; Google insisted on rephrasing what I had written, resulting in making my search more difficult.
I went to startpage to check it out and it says “enhanced by google” 
Click on the box under the search strip. Among other things it says:
Google, but I’m a lot less happy about it than I used to be.
I just tried Bothell Washington. I got population and a map of city boundaries and nothing else.
Did the same with google and got the same map and wiki has a bunch of information, and a bunch of other links.
Conclusion:
wolframalpha still sucks
Edit:
I noticed screen said something like “computation timed out” so I just tried it again
It came back with more info this time, but just stats on crime, income etc. Nice, but hardly a competitor to google
Also, the fact that it timed out the first time is in the “sucks” category
In 1994, I started with webcrawler.
Then it was Lycos.
Then it was Alta Vista.
Then Google.
I used bing earlier today on my iPad. I was trying to google something, but google kept timing out on me! It was annoying…
I used to google, but not since I duckduckgo.
