Heard of Wikirank? It’s a promising and useful tool.

What is Wikirank?

Wikirank shows you what people are reading on Wikipedia. It’s based on the actual usage data from the Wikipedia servers, which the Wikimedia foundation makes available as a public service. They take that data, process it, and give it back to you in a format that’s easy to use and share. Wikirank reveals emerging trends, and lets you embed relevant charts in blog posts and on social media sites. All in all it’s a really cool tool for that elusive niche research toolbox I never seem to get finished
