Wikipedia is by far one of the most useful sites on the Web - at least to me. That's why I am looking forward to seeing what Jimmy Wales and crew come up with when they launch their new search engine. In the meantime, there is a new Wikipedia tool, however, that has caught my attention - Similpedia.
Similpedia takes any links and shows you related content from Wikipedia. It's extremely handy if you want to drill down into a subject. Even better, they give you a bookmarklet that makes this all a snap to use from any site. You can also add a contextual widget to your site that pulls up related content for your readers and even track results via RSS. Bigger plans are in the works - a site for news and blogs called Similario.
This is a taste of what can be done with Wikipedia's vast stores of data. I would love to see Wikimedia take this to the next level with a robust API.
