I came to know that blogger blog (blogspot.com) is blocked by some organizations.
Since we are also using blogger blog, our blog also is not viewable within network of some organizations.
So, we are showing the latest posts of our blogs in our website also using RSS Feeds.
You can see it here.
And, you can forward this url http://www.qualitypointtech.net/blog.php to your friends who are not able to view blogspot blogs.
