Yes, Ashwin.
Tamil community has started working on these. Most of the topics seem
matching the popular interest (Our most visited article is Sachin
Tendulkar) and home work needs of school students :)

doesn't make sense.
Bengali community needs to verify if the reporting is unusual.
I have also pinged the developer to get stats for all Indian language
projects.
