Twitturls allows you to check out the most popular links being tweeted on Twitter as they happen. The site lists the links based on popularity and when they were posted.
An icon next to each link shows in what direction the link is going in popularity. A red arrow means that the link is being tweeted by practically everyone, a yellow arrow means that the link is warming up to that level, and the blue arrows mean that the link has remained pretty steady over the past 24 hours and shows if it is now climbing or falling in the ranks. To maintain the quality of the links, there’s a link you can click next to each link to report if it is spam. Currently the red arrow on the page is a link to a TechCrunch post on “PR Secrets for Startups” and one of the most popular links today is a Mashable post listing over 140 Twitter tools.
