The question has transgressed from "Is local language talk for real?" to "Why local language talk is not happening on mobile?"
For an example, Let us take the persona of Mr.Mungerilal, living in my city of Pune.
Mr.Mungerilal's ancestors have been living in the Peth area of the city since ages. Mungeri , 30 years of age, works in a small manufacturing firm off, Laxmi Road.
He wakes up in the morning with a copy of most popular Marathi newspaper, "Lokmat" and a cup of tea. Once his inquisitiveness is satiated, he walks of the office. During his spare time, he listens to local FM stations on his mobile phone, wherein the RJ usually speak in Marathi.
In between, there are pings on his mobile phone from Whatsapp sent by his friends and not-so-friends, but he dutifully checks all of them, much to the annoyance of his employer, Mr.Deshmukh.
During lunch, his free time is devoted to checking, the facebook stream and watching the cool videos, far from the prying eyes of Mr.Deshmukh.
Back at home, Mr.Mungeri snatches the remote and perches himself in front of the TV with couple of Vada-Paavs from "Joshi Vadeywaaley" and flicks on ETV - Marathi. He alternates between, DD-Sahyadri, Colors Marathi and Zee Marathi.
Tired from the day's work, he has "Varan-bhaat" and off he goes to dreamland, wondering where is his soul-mate.
This is the typical native language power user, who is very active on all the offline mediums of his native lanuage, but his activity on digital medium is limited to two walled gardens and it suffices his purpose.
The question is, how do we get Mr.Mungeri to be more digitally active in his native lanuage, other than the two walled gardens?
