There will never be one single tool that fits all use cases and needs. I'm happy with friendica, it fits my needs, but it is not perfect. None of the FLOSS socnets are-the W3C Social WG and the eventual adoption of the results by the various networks will be a step into the right direction.

What I missed in Sazius list of networks is eMail though--or do you only use it for "work related" things? It's also a big socnet for me.
