Asking about alternatives

Pandia has covered the Ask story as have many others, and they're also considering possible alternatives for the coveted 4th spot. They mention Gigablast (though given the freshness test that I tried the other day I still have my doubts) but they are also looking at Exalead as a strong contender, particularly because it's a firm favourite with librarians because of the advanced search functionality. Can't say that I disagree, especially since that was my feeling the other day as well.
