BackTweets
With Backtweets you simply enter a URL (the service will auto-resolve shortened ones) and it will deliver a reverse-chronological list of tweets containing the requested link.
In addition, it provides an RSS feed so that you can be notified automatically as new relevant tweets appear. This is a simple way to monitor your brand/website on Twitter.
BackTweets also provides a search bookmarklet that makes it even simpler to get the search done.
An example search for http://twitdom.com/ is shown below.

Traffic rankings are sourced from multiple sources, if available, for the Twitter application. This includes Alexa, and Compete rankings.
