I tried "ethnic groups nigeria". Wolfram Alpha gave me a |-delimited string of them, Wikipedia gave me a much more comprehensive list (http://en.wikipedia.org/wiki/Category:Ethnic_groups_in_Niger...) and each one is a hyperlink.

Perhaps the author prefers to use Wikipedia for "facts and trivia", but I find myself enjoying the site for providing a detailed and thorough introduction to almost every non-trivial topic.

That's what Wikipedia's good for. It's not nearly as good at what Wolfram is trying to do, which is to process and comprehend complicated data analysis. They're two entirely separate things.
