It had been some time since Facebook released their new Send Button.The Send button is a social plugin that websites can use to let people send a link to a friend through Facebook Messages, post it to a Group, or email it to an individual. Follow this tutorial to add it to your Blogger Blog.
Configure how your Send button should look like, using the options below, and then continue following the instructions in this tutorial.
Demo
1. Login to your Blogger Dashboard, and navigate to Design > Edit HTML.
2. Click on the checkbox which says “Expand Widget Templates”
3. Look for <data:post.body/> and immediately below that paste the following code.
<div>
<b:if cond='data:post.isFirstPost'>
<script>(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));</script>
</b:if>
<fb:send expr:href="data:post.canonicalUrl" font="arial" colorscheme="light"></fb:send>
</div>
5.Next you have to add the fb namespace to your template tag.Your template should have the specification for the fb tag that you have used. The following namespace declaration will take care of that. To declare the namespace, find
<html
and change it to
<html xmlns:fb="https://www.facebook.com/2008/fbml"
The following screenshot will help you out.
6. Save your template, and now you should have the send button working on your blog.
Hmmmm I want something more than the plain send button!!
In that case, you can use the Facebook like button which can accommodate a send button along with it. To know more about the usage, refer the following post.

Facebook Comments can bring better interactivity into your Blog. These comments will work like a Facebook Wall.This tutorial will help you to easily setup Facebook Commenting on your Blogger Blog.
Facebook has now released an improved version of its like Button. The new Facebook like button looks like the horizontal version of the Official Tweet Button. The Facebook Like button will show the no of likes just like the tweet button does.The like button has some changes from the older version in the way the user is allowed to like and unlike. 
Choose Website from the drop down list and provide the Page name in the next box. Read and agree to the terms and click the “Get Started” button.
It may take some time for your posts to appear on your Fan Page Wall(your latest 25 posts). From now on every new post that you make will be automatically posted to your Fan Page’s Wall.There might be some delay in the wall getting updated, as RSS Graffiti checks the feed for new entries at regular time intervals.(If you want to post to your profile Wall as well, then in RSS Graffiti, click on your name and add the feed there as well)
