Google Buzz, the service which is integrated into Gmail allows you to publish latest updates similar to what Twitter offers but offers you with no limits, Images & Videos etc. This service can also be considered similar to Yahoo Meme whose updates were also shown on wordpress. The plugin can be downloaded here. Here is more information on the same.
Features:
* Caching – you can setup caching of buzz posts for faster loading of your website
* Number of posts – You can limit number of posts to display from Buzz feed
* Widget ready – After installation you can frag and drop widget to your sidebar
The installation is same as any other wordpress plugin, but while you need to setup, you need to edit one line of the file, so that the plugin displays your Google Profile updates and not the default one. This plugin displays google Buzz feeds. It’s easy to set up + you have possibilities to set feeds to cache every X minutes and you can configure how many seconds you want to wait for response before display cached feed.

$feedURL = 'http://buzz.googleapis.com/feeds/{user}/public/posted';
Instead of the USER , you need to enter your Google Profile Name there and this starts working getting all the feed updates displayed.
