This is how we are going to do it:
1. Visit facebook developers social plugins page
2.Click on any one of these links to create your plugin(eg:comments)
3. Enter the desired characteristics in specified boxes.
4.Facebook shows how the plugin will look like on your blog.
5. Insert the code on the desired portion of your blog,facebook starts working on your blog.
6. Since I am not very adept at the designing part, I use the Quick Adsense plugin to insert codes into different parts of my blog at ease.You can try it out, it is free and makes blogging easy.
I have used like box, comments and live stream on my blog, and I am sure these plugins have made my blog lot more interesting(though I am waiting for the first comment!)
