About Jolla support open media like diaspora:

You do realise that diaspora API is not yet ready?

https://github.com/diaspora/diaspora/wiki/API-v1

However I think the mer community definitivly should take a look and make it work in nemo at first. The "social media plugin API" are the same used in sailfish AFAIK so its should not be that hard make it work on saifish too. But dont expect Jolla to prioritize this when diaspora API not even near to stable.

Btw. To start a flamewar, RubyOnRails sucks bigtime. I prefer web2py and DJango over RubyOnRails. What a shame diaspore using RoR
