I work with a guy who writes weekly columns online, which in turn are frequently tweeted and retweeted. I'm trying to find an effective way to tabulate the frequency with which his column is tweeted. In other words, how many twitter feeds does it wind up in?

I've built a lot of such trackers in the past for various former employers, but if your co-worker doesn't mind a little manual work it's pretty simple. At any time you can enter the full canonical URL (minus any query strings or parameters tacked onto the end) into the Twitter search box on twitter.com, and you'll see everyone who has shared that URL.
