Yes, Thanks @pradeepkumar for asking this:
I am an Indiblogger, and also I share at:
Quora intermittently, and a good number of other sites which is available on the sharebutton
And of course a major number of FB forums, and Groups.
This is apart from the major platforms like twitter, G+ Digg, and many others
I appreciate your initiative to start the social bookmarking websites list.
PS: Of course apart from these above sites, I do make mention some of my posts on my other pages like newsandviewsforyou.com and my blogger.com pages too I use as a promotional platform.
