Maybe there is chance for Bing but definitely not Yahoo. The first reply was funny and it's quite true. The internet would definitely change if Bing took over.
So many of these threads have popped up all over the web because people are upset that their websites were penalized by Google and that they are to "controlling" over SEO. Google has changed SEO for a good reason, quality results rather than spammy 1 page sites that everyone makes to try and form an income. Quite frankly, both Bing and Yahoo won't compete with Google on a serious level.
Google is going to seal their own fate and yes yahoo and bing will take over, greed will get the best of Google. They are already down for the quarter.
Heck no, Yahoo and Bing such majorly. I think both of them produce too many sponsored links disguised as real search results. The results in general are horrible, Either its something with them not wanting to display any competitor's results or what but I think they both stink. When I get a computer that has bing or yahoo as default engine I change it to google fast.
I don't think so. google have a big assets, but yahoo not need money and still improving content and features. same as bing..
The only way anyone is going to overtake Google is if Google themselves do something to alienate their customer base, no-one is going to be able to take that much custom from them by their own efforts.
