I haven't worked at Yahoo in years, but I'd be very surprised if they shut down Answers. It was the most successful new product launch they had in a very long time, and it looks like it's still thriving today (take a look at the Answers homepage - there are several new questions being posted per minute!)

Compare to the products mentioned in the blog post, most if which I hadn't even heard of. Why would Yahoo continue to run a message board product when they also have the much more popular Yahoo Groups?
