Today's the deadline for the Feedster Developer Contest, and I'm about to send them my submission: A Firefox extension that displays related links, via Feedster, within article pages on the Washington Post and New York Times Web sites.
With the extension installed, you should see a "Links via Feedster" box on every washingtonpost.com or nytimes.com article. The box will contain a list of links to pages (usually on weblogs) that link to the article you're reading -- so that you can read what other people think of the article.
Here's an example of what it looks like on the Post's site:
And here's the NYT equivalent:
If no Feedster links are found, you'll see a "No links found" message within the box. You also might see "Loading..." within the box, if Feedster is being slow.
Here's the extension:
Install it by clicking on it in Mozilla Firefox. You might have to explicitly "trust" this site as an extension provider, depending on which version of Firefox you're using.
IMPORTANT NOTE: By installing this, you acknowledge that the "Comments on this story" boxes are placed automatically by the extension, not by the Washington Post or New York Times themselves. Obviously, the newspapers are not to blame for any inappropriate links, strange juxtapositions...or anything, really. Also, Feedster does not necessarily endorse this extension.
UPDATE, Dec. 13: I've released version 0.2 of the extension. It's now been renamed to "News Story Expander" and includes direct, deep links to Feedster searches within the dynamically-created sidebar boxes. The link above now points to the new version.
The new version installs cleanly over the old version.
