It's Peter-Paul Koch. He's well known for providing painstakingly detailed tests and compatibility tables on browser capabilities and web standards support, particularly js.
I'm not sure what stats are like for users of the specific devices he's looking at here, but India's a big market: I'm guessing browser compatibility here is going to be of some interest to more than one or two folks.
I think the problem is that out of the context of the blog, the title makes it sound like it's going to be more interesting to the average reader than it actually is.
If you're reading his blog anyway, you'll probably be aware that much of it is about compatibility questions in browsers and wouldn't be surprised that an article on Indian phones is likely to be related to that.
Just seeing the headline in isolation, I was (and I suspect you were) expecting much more "weirdness" - odd shapes, strange keyboard choices, obscure OS options etc.
That's not a fault of the blog, just a result of seeing a headline outside its context.
