There has been a lot of recent news on Accoona, a search engine "with interactive tools that provides users with better web, business and news results; powered by proprietary Artificial Intelligence technology." The news is that Accoona Relaunches 'AI Search' Engine specifically "targeting media outlets and businesses."
So I dug up a thread on this news at DigitalPoint Forums and found that most of those that replied to the thread think Accoona is a poor search engine. In fact, one member created a site named Acoona Sucks based on his initial experience with it. Why does Acoona suck? Because they have a representative joining forums and posting information about Acoona without telling the forum folks that they are from Acoona and have a bias. To be fair, it looks like they have posted under their name in the past, back in March, here and here.
So does Accoona suck or is it not that bad? Forum discussion at DigitalPoint Forums.
