Those saying translation is not neccessary are themself not really hindi lovers. I am blogger average views of 10 million per month and post only in hindi. And all my readers are hindi readers. And i too love to see posts in my own country language i.e. Hindi.
Let me just say this buddy, India is a diverse country with many languages and Hindi is not a national language as there are over twenty languages that hold the same importance in different states around the country and with a country with around three hundred languages it is hard to find a balance.
@OP English is a common language here in India and so most of them understand and communicate in English and if you are able to convert to different local languages ,then it would be great.
