Tons of support for Twitter lists this week, coming from a new list directory called Listorious and the Seesmic desktop client. That’s dandy.

Twitter lists emerged in the past two weeks as a beta feature for better organizing Twitter content and Twitter contacts. Bubblicious founder Brian Solis mentioned the new feature when it first launched. The potential for Twitter lists is easily recognized, as many third party applications already had some form of group functionality for filtering Twitter content. With Twitter introducing the new functionality along with limited API support, third parties are quick to begin playing with the new capabilities for streamlining users’ Twitter experience.

As a directory, Listorious offers both search and recommendations for Twitter lists. Listorious has smartly integrated with Twitter sign-in, so that any actions taken on the site are immediately reflected within your Twitter account without any redirection. Similar to a blog network and search tool, Listorious extends itself as a single access point specifically for list-related Twitter actions. The result is a useful application for those seeking lists to follow.

This likeness to a blog network indicates the direction in which the Listorious site may head, taking cues from established network catalogs and other recommendation tools. Any success Listorious sees will be attributed to a healthy interest in Twitter lists, as the improved delineation of Twitter content provides the value many users have been seeking from Twitter. That being said, Twitter lists are also likely to act as separate online publications in their own right, further combining the facets of a chat room, forum, instant messenger and blog with comment streams.

The renewed interest in Twitter has provided a unique opportunity for Twitter, developers and end users, as the ability to better filter and consume content means that Twitter has smarter usability. While there is still a great deal of development needing to take place around Twitter lists, the Listorious launch offers a peek at the future potential of recommendation tools designed around Twitter.

The current drawbacks of Twitter lists, the API and developing around the new features, however, are somewhat evident in the Seemic support of them. Typical of Seesmic’s insistence on being first to market with integrated feature implementation, the desktop client has added Twitter list support shortly after the feature was announced and offered on a wider scale to Twitter users. That means that there are still a few bugs to be worked out, but the current capacity of Seesmic with its new support for Twitter lists is a unique and interesting look into the future of Twitter lists and desktop applications.

As Seesmic wasn’t designed specifically as a Twitter app, there’s more to Seesmic than just its potential to post content to Twitter. Nevertheless, Seesmic’s dedication to remaining an open and fluid application for cross-network use makes it a great experimental tool in social media.

Seesmic’s integration of Twitter lists provides a useful way to organize relevant content directly within the desktop client, making it even easier to employ remote Twitter management through its application. Remotely interacting with Twitter has become par for the course, with several third party apps providing a good amount of value to Twitter users. The introduction of Twitter lists may endure a deeper interest in Twitter app development, which seems to be the case considering the developments we’ve already seen this week.
