I actually thought to email the developer of WP-Google Buzz wordpress plugin that adds Google Buzz feature to your Blog, regarding the Alignment. Yes, the Retweet button which i am using one is from Topsy, even the previous one Tweetmeme provides the option to align the button either in right or left side of the article. Till yesterday, the WP-Google Buzz plugin doesnt provide such option to its users.
Still, the plugin missing with the manual alignment feature. Where the user can modify the div tag options simply from the plugin dashboard page. Hope to see this in next update. The developer recognized it and added the feature in his recent update done today. Now it will make my blog look more good for buzzers 🙂 Have fun !
