In general paid wall content makes sense in niche markets. Despite the fact that I enjoy reading world news, somehow I have a feeling of their content being propaganda material designed to manipulate the opinions. Growing up in Serbia certainly creates a very specific attitude towards the media.
Other than the content, the user-experience of the application completely misses the mark with all the advertising. The paywall is designed so you don’t need to go through the advertising.
Once my monthly trial expires I will be shutting down the service. In the world of free information, disregard for user experience will cost you your user base.
