Jargong impressed me when I first got in to see the site. It does way way way more than Twitter. So go read that ifno for Flickr and all the chat client support. But as for Twitter: 
* View “Me and friends”, “Everyone”, “Friend list” and “Follower list” timelines.
* Automatically refresh (every two minutes) “Me and friends” timeline if you want. Set automatic or manual refresh in “My settings”.
* When logging in to Jargong the client can automatically fetch your status message from Twitter and set it as your IM status message. Turn this feature on or off in “My settings”.
* When updating your IM status message in Jargong the status message in Twitter can automatically be updated. Turn this feature on or off in “My settings”.
