Hello interesting thoughts here, it is true that project blank aims to revolutionize twitter, give people the freedom to express themselves, rather than live based on the ideas initiated by the centralized authorities. Through Hive ecosystem, we've been able to do this the right way, a variety of communities that have been banned from other social mediums like facebook are able to gain their freedom on hive.

But i doubt the possibility of a whatsapp with Leofinance, I understand that anything is possible, but technically, whatsapp is an instant messenger, while applications like twitter are quite different being a social media app, why will anyone want to store their chats on a blockchain? But you know, maybe some second layer solution will eventually come up that will handle the data storage in a way that doesnt buggle up the chain. Anything is possible..

Interesting thoughts....keep them coming.
