Notifications to social nets

I just had a chat with an admin of a Russian couch surfing group on VK, and he had this idea.
So, when notifications are up and it’s possible to connect Couchers account with social nets, could it be possible to send the notifications not to email, but to a social net you linked to your account? Not by default of course, but as an option. Could be useful even when there are Couchers apps already because people might not want to install another app or not have the space for it on their phones. They still would probably want to be informed about messages/requests, and a lot of people don’t really check their emails.
I don’t understand anything about development, but the guy who suggested this said it should be not too difficult to implement?
