I started to switch everything (cloud stuff, Android) to open source that I can host myself in case I need to in the future.

I've switched to Owncloud, hosted at Hetzner. It was really easy to install and does pretty much everything I want (RSS reader, Dropbox clone, contacts, calender, Google Music clone).

I tried Newsblur, but the interface was too complicated for my taste and the Android app was not very stable.
