Dear Rediff, the name change from Bangalore to Bengalooru was proposed sometime during HDK regime and it is NOT officially signed yet and an ordinance has NOT yet been passed by the parliament. Heck, Karnataka does not even have a Government right now.
Please do not get carried away and start referring it as Bengalooru. Let the order gets passed. Then we will go with the new name.
I know being a native of Karnataka, we always call it as: Bengalooru (even when we write the boards on KSRTC buses).
But let it become official. Hold your horses till then.
