But what about the "correctness" of the search results? Well correctness is quite relative, what I intend is the results expected by the user. Let's give it a try. Assume I see the following image somewhere and I want to perform a search for it.
So I'd enter a query like "bloggers dilemma" (since that's what's written in the image).
Searching on Google Images gives be on the first page containing 18 images, 9 correct results. Here's the query.
Searching on Bing (here's the query), I scrolled over about 500 images without 1 (expected) hit. That's bad, not what I expected given the nice interface etc. But ok, it's still in beta (being officially online just for a couple of days now), so I expect better results in the near future.
These queries bring slightly better results for Bing, but still...
