It's so "amazing" that fails to index many sites indexed by google. Try to search for some really rare words and compare the results. Google usually will beat Bing by 2 times more results or so and much faster indexing.

And if you happen to create your own web site and then bother self with access logs analisys, you will see that Google learns about your site quickly and then re-indexing it on a regular basis. But hey, where you are, crawlers from bing? Looks like Google beats bing to the hell when it comes to infrastructure capable of indexing things anyhow quickly. And since web is a dynamic thing, bing really sucks. They're such a pathetic losers that Google even caught 'em copying their search results. It's obvious that you -> google search is faster than you -> bing -> google search, and it's unlikely that Bing "proxy" could be some privacy enhancement .

So, why I should use this third-rate service? Just because MS paid to Nokia? Hardly my fault - I do not want to use third-rate services just because Nokia wants this.
