Just came across a new service that’s been officially approved by Twitter.com: introducing TweepML, an XML based format for sharing lists of twitter user accounts. If you know what OPML is then you already know the concept behind TweepML, it provides a free universal framework for importing, exporting and creating twitter ‘groups’ that can be shared or even stored as a backup of important accounts. The main website, www.tweepml.org, also includes a free follow tool that helps streamline following lists of users via your twitter account.

On the site it has various libraries and examples available to aid developers in implementing TweepML into new or existing apps. Currently the most popular lists seem to be the ones with the largest number of followers. I’d be willing to bet good money that this is already being used by spammers and/or marketers to cultivate their own twitter accounts targeting various ‘groups’ featured on the site…but then again, almost every tool or platform that is useful has the potential for grey/blackhat usage.

Interesting new format, it’s definitely going to make twitter account sharing (not to mention account duplication) a lot easier!
