Billing is based on usage for load balancers. You can't offer fixed monthly fee as users may consume all of your network or system capacity and pay as if they were using nothing. This is not a sustainable business.
DO is cheap, you can achieve scaling and failover for a lower fee than with AWS. Their new load balancing solution is nice but lacks features and its price is 3x higher than what we provide at https://pikacloud.com.
We use some responsive design for screen size. I have to optimize some UI action for tablets and mobiles. We will maybe publish a mobile app if customers ask for it.
I understand your point of view, we saw an avalanche of competitors since Google Reader death announcement. Some projects will emerge as the new leader of this market.
I have launched other projects such as Pikacode.com (Git/mercurial hosting) which is "yet another GitHub" but running since 2008 for thousands of users. So my work can be seen as a side project but with true conviction and dedication for quality and support over time.
Work can be achieved to push the limits of RSS technology. Building offline contents from feeds, mobile readers, media aggregations (for example magazine build from RSS articles)...
Thanks for the suggestion. I have to add some screen shots.
The 5 rss feed limit is part of our business model. Feeds consume resources and resources cost money. So we have to cover our expenses to ensure a reliable and durable service.
You are right, competition is good in this market. We are trying to create easy to use software. Github and bitbucket are both awesome products and Pikacode wants to provide similar service but with different implementation such as Scrum features and team work.
