well. one simple reason is that i would have no idea what you are writing. now you could be posting death threats to our beloved prime minister in tamil or telugu and i would have no way to find that out! that would get 'me' into trouble. so i had rather have the primary language of the content here in english. to keep things sane. sure a line here and there in your local dialect is ok. hell even i post in hindi sometimes out of frustration. but yes... english is what we roll here. cheers.
