Search Wikia, il primo motore di ricerca collaborativo, chiude, lo ha annunciato ieri Jimmy Wales sul suo blog:

while I personally believe in the opportunity for free software to make serious inroads into the search space, our project, Wikia Search, has not been enjoying the kind of success that we had hoped.
In a different economy, we would continue to fund Wikia Search indefinitely. It’s something I care about deeply. I will return to again and again in my career to search, either as an investor, a contributor, a donor, or a cheerleader.
But for now, we will be closing the doors on the Wikia Search project (as of March 31, 2009) and will be re-directing and refocusing resources on other Wikia.com properties, especially on Wikianswers.
