Used the platform for three long years before switching to Azure which was a pain. This platform has a cleaner UI. AWS, Azure is z main to setup. It's not just the PaaS service that DO provides. Server creation and scaling is flawless here. Not to say AWS or Azure don't have their functions.
Why alignate paying customers? The good folks on Twitter (@digitalocean) --explained prepaid cards or bitcoins are accepted. Now that Do have gone public. Can we expect any changes?
