TweetDeck. Available on Mac, PC, Linux, iPhone, iPod Touch, iPad... and now Android. While not officially launched, the beta available now (
go here to sign up to get access) is a smooth running beast of a social app for Android 2.0+.
TweetDeck has evolved a bit from being just a Twitter client, allowing you to add columns for your Facebook, FourSquare, Google Buzz and such. The Android version evolves even further, throwing all of your updates into a blended "Home" column. The "Me" tab shows you what your friends on your social networks are saying about you, be it replies, likes, or comments.

Also new in the Android version is a completely redesigned UI thats streamlined to look exquisitely minimal (while being useful) on a mobile display. New things are tinged yellow, and the timeline of your stream sits out of the way in the header bar. Four buttons on the bottom give you access to the main features. The post button lets you toggle the update page. Toggle the social networks you want to ping and tweet, photo post, or geotag away.

TweetDeck's "sending notification" is very cool and very Android; instead of posting a pop up or even a loading icon, the Tweetdeck developers took the option to send the uploading msg to the Android notication pane, allowing the user to hit send and immediately get back to his "networking."

TweetDeck seems to think you have at least 12 friends that you would like quick access to, and gives you 12 slots to plug them in. TweetDeck also takes it upon itself to add your own accounts to the quick access panel which is nice for a narcissist like me.

Checking out a tweet leads you to three easy to tap buttons to fave or retort and if you feel that strongly about it, a map that shows just where you can go and smack that bitch in the face. Even tells you how far you have to go till she gets that ass whoopin. Yfrog seems to still be Tweetdecks photouploader of choice and will load a preview of their photo links below the map (if there was a geotag).

But maybe you like this person (or stuff) and want to stalk this person check out his tweets. You can even add his feed as one of your columns (wink, wink). BTW narcissists, your profile is where you add columns for mentions, direct messages, or any of the lists you created. I would say the method of adding columns is a bit hidden, though I somehow agree with their reasoning.

Search is.. well... twitter search. Add a column if you wanna. Track a topic, or a democratic daddy.

The map spews everything local and Foursquare sorta lives here (and Buzz? Didn't test that account but I reckon yea.) Nice execution.

Interesting fact, the Menu button only works on the home page, where you can refresh, access your accounts ( you can't delete accounts yet.), or manage your columns, and turn on/off notifications. One setting I wish TweetDeck for Android had was a sync setting, it looks like it pulls every five minutes. Android says it uses about 5% of the battery...

Other than that, Im really impressed with this Android app. This is a fine example of an application built well, designed with effort, and heading in the right direction in user interfaces. I sincerely hope people try to emulate this look. There's definitely a few bugs, but still far more stable than even some Google apps.
