Research & Relationships with Twitter Lists

Twitter Lists. They were introduced (slowly) a few weeks back, and, largely, confusion still reigns. Do I make a list? Whose lists am I on? What exactly are these darned things for? I can't answer all the questions, but I have found out a few things about Twitter Lists that I'd like to share:

1. They're useful for finding new resources & connections. Example: I was looking to connect with non-profit science education organizations and museums in regards to an upcoming project. Before Twitter Lists, I'd go to websites like We Follow and Twellow, where users put themselves into groups. Due to the opt-in nature of these sites, I was missing out on anyone who just hadn't updated their directory entry. Now, with Twitter lists, users are creating their own groups of the followers they find most valuable. That said...
2. They add a degree of credibility to an account. Before, you could assume a user was a spammer if they were following, oh, 1200 people and had about 50 followers. Now, you can also glance at how many lists they're on. 20,000 followers and 9 lists, none of which pertain to your interests? Might not be in it for the conversation. And, if you're a selective follower, you can glance through the lists a user is on to see what you have in common.
3. Application integration will be key. Twitter has spent a lot of time over the past month improving their web interface. Tweets now automatically refresh, and the same goes when you're viewing users within a Twitter List. But, if you're loyal to an application (like me!), integrating Twitter lists into an app like Tweetdeck will make your social media life infinitely easier. Example: I live in Dallas, and want to know what other Dallas Twitter-ers are up to. There are several lists to choose from (a little homework never hurt!), but once I decide, I can import that list into an application and voila! Those updates load like a group or column. (Ideally. Seesmic Desktop currently offers integration, while TweetDeck does not)

Twitter Lists can be used to save you, or your organization, time as well as help enhance the conversations you have. What other uses have you found for Lists?
