Wave wasn't just laggy, it was frequently down. All sorts of apps with scaling issues can work better with the Sandstorm model. The whole Sandstorm idea really started clicking for me when I read one of their earlier posts on motivations: https://blog.sandstorm.io/news/2014-07-21-open-source-web-ap...
Good read, thanks. Is it possible to run an own, modified version of an open source app on sandstorm.io? As a non-techie user? Like - say - a small modification of Wordpress?
That made me a backer.
