After trying several Android Apps to replace my HTC Peep, I came across Seesmic. At first I have a problem with its support to Google Buzz but I quickly dismissed that doubt after I try it in my Tattoo.
It also support a widget for your homescreen where it will shown a randow tweet or buzz. It can send your buzz/tweet to multiple account too.
One thing that makes me wonder is how in the world that Seesmic can still access Twitter using its old authentication model instead of the new OAuth scheme. Although its used OAuth in Google Buzz when I add my Buzz account in it.
Download it from Android Market or download it to your computer first via http://seesmic-android.en.softonic.com/phones.
