Earlier this week, Seesmic rolled out support for the new Twitter Lists for its Desktop client. Today, that same functionality comes to its web-based client . And with it comes a bonus: Geolocation support. Now, to be clear, most users still won't be able to use this geolocation support just yet, as Twitter has yet to enable it for most users. But if you do happen to have it, Seesmic supports it. As you can see in the screenshot, it looks pretty nice. If you see a little location marker on a tweet, you can hover over it to bring up a Google Map overlay showing where that tweet was sent from.
