I was intrigued by this Google Chrome extension. (It also installs in Opera).
As in the “About” function, it only does one thing…
My immediate thought about a use for it is to check essay content if you suspect that a bunch of text has simply been copied and pasted from the Wikipedia. Of course, content can certainly be legitimately used within writing provided that it’s properly referenced.
Further than that though, Qikipedia is Open Source software and so clicking on the “View Source” like directs you to the source for the project. It’s good reading for the programmer in you.
You can find the extension on the Chrome Webstore here – https://chrome.google.com/webstore/search/qikipedia
