Continuing the "Ideas are Cheap" series, here's another simple idea that I would personally find very useful but would be difficult to execute in terms of content.
These days I'm finding it hard to read Kannada newspapers because my vocabulary is clearly lacking, and consequently I would probably never get to read novels by Kannada novelists like Shivaram Karanth and other respected writers.
On the other side, there has been an influx of a lot of people from outside Karnataka into Bengaluru in the past few years. Since you can easily get by in Bengaluru with English or Hindi, most of them don't learn Kannada even though many of them would like to.
What if there were word lists for Kannada just like GRE/TOEFL to improve people’s vocabulary? But in a more fun setting on the lines of what DailyLit is doing - they email you 1-2 pages of a book each day, so if you read your email each day, you'll end up reading a book as well.
It can also be done similar to what @rajeshlalwani has done with his hindi word of the day series on twitter.
