The question of language

Currently wondering: What is the best language to write in, as a multi-lingual person on the internet who blogs daily? Is it better to write in Hindi or Marathi, given how little internet writing exists in these languages, how little is record of the people who speak these languages? Or is it better to write in English as an Indian because that would mean that those who can’t read Hindi or Marathi won’t be excluded? But then, what is more important–not excluding the latter or including those who don’t know English? Should I write everything in all three languages? Or are certain thoughts and ideas expressed better in one language than another? How does one choose a tongue?
