What's the trend in Wikipedia?

There is a brand new Wikipedia related website Wikirank.com.
Wikirank helps you to analyze different topics in Wikipedia (as of now only English).

You can check how many times an article has been viewed in a time-line, compare viewing rate of up to four different articles and you can even get an embedding code of this comparison to put in your web sites or blogs.
This project sounds promising but currently only English Wikipedia is supported.
