I visited your blog and I have seen the following facebook,twitter meta tag in your blogger template
<meta content='Facebook App ID here' property='fb:app_id'/>
<meta content='Facebook Admin ID here' property='fb:admins'/>
<meta content='@username' name='twitter:site'/>
<meta content='@username' name='twitter:creator'/>
In the above code, you need to add your facebook app ID and Admin id and also your twitter username and your blog's username of twitter.
