Quality issues
The article definitely deserves it "B-class" status. It is poorly organized and the quality of English at some places is poor.
Where are the Telugu scholars and PhDs? Maybe someone should ask professors from Government universities to contribute to wikipedia - they do have a lot of time on their hands. Unfortunately, I do not have enough knowledge in this area to edit what has been written. 
I have removed some (rather poorly written) sections which contained redundant information (on Telugu for example-there is a page for the language and related issues).
