Before asking these kind of questions in a public forum like this, be sure of what you are posting. The proposed change is not Bangalooru, but bengalooru.
It is a very good decision on part of government of Karnataka to implement this change. As many readers pointed out here, compared to changes that happened in case of Chennai, Mumbai or Kolkatta, bangalore to 'bengalooru' is not a big change.
Like wise, mangalore to mangalooru, mysore to mysooru, belgaum to belagaavi....
