I don't trust the masses enough to think that Idka would become a major success. All your data is encrypted even when in transit. You can delete your content forever if you wish it. But after the beta, users will have to pay €1 per month and most people would rather flock towards the free services.

The best case scenario would be to expect people to treat STEEM as a public blog and ave them be on Idka for more personal content. I don't think it will become a smash hit. But it's the best Hunt I've seen today. Resteemed for extra visibility.
