Hacking around I found a way to solve the above issue and that can give you a freedom from plugins and hefty set-ups to automate WordPress article posting to Facebook and Twitter page/account. Here is the way:

  1. Have your Google Feedburner account. [bs_button size=”sm” type=”info” value=”Link” href=”http://feedburner.google.com/”]
  2. Connect your wordpress site/blog with Twitter account. [bs_button size=”sm” type=”info” value=”Read this..” href=”http://adsenseforfeeds.blogspot.in/2009/12/socializing-your-feed-with-twitter.html”]
  3. Then connect your Twitter account with Facebook. Just complete the set-up by Settings -> Profile -> Facebook . This will auto-post to your Facebook account.
