I've recently set up my own KVM-based vServer that runs Trisquel.
It hosts email, statusnet and GNU MediaGoblin.
MediaGoblin is reachable via http://www.isengaara.de/.
I installed MediaGoblin because other mediahubs such as http://vocano.de/ use
the nonfree flashplayer vor video playback. The also recommend other nonfree
softwares. If you know the youtube url than you can watch the videos without
nonfree software.
For email services I quote from Richard Stallman:
"The two ethical issues for an email service are (1) whether you can use it
without running any nonfree software (including nonfree Javascript code from
the site), and (2) whether it respects your privacy.
Last I heard, Gmail was satisfactory on issue 1, and probably so are many
others. On issue 2, I have no way to verify that any email service is
satisfactory. Therefore, I have no recommendation to offer.
However, I can suggest that it may be wise to use an email service that is
not connected with your search engine. That way you can be almost sure that
your email contents don't influence your search results. You shouldn't
identify yourself to your search engine in any case."
Recently I heard about https://fripost.org/index.en.html which is maintained
by fellows of the FSFE.
