To do that, I guess, 1mb or similar businesses could add capability to create a website, post to it, update it via something as ubiquitous as WhatsApp, kind of like a Tumblr or posterous clone; add ability to accept payments, sell things.
Curiously, among my friends, telegram is used to consume content. They subscribe to telegram-channels and simply search for content posted and browse it right from the app. Much like how YouTube has replaced games, and Instagram has replaced Facebook, telegram in a sense has replaced Google/Browser.
Perhaps, someone needs to invent a new kind of web that is in symbiosis with WhatsApp or these other very popular apps. I guess that is exactly what Meesho [0] is doing, but not quite? May be some business like 1mb will figure it all out.
