Yes here is a blog in Rk's name. I presume it is his blog and not just someone using his name. Authenticity of the blog is trivial. The blog posts are entertaining in a unique way while at the same time they comment on serious issues. Read here. Do read it, you will enjoy.

RK also posts Chaitanya Kunte's post on Barkha Dutt which he removed after NDTV exerted pressure. He challenges NDTV to take him on.

Down with Barkha. Am I in trouble now?
