There are many good alternatives to centralized social networks:

Diaspora: https://diasporafoundation.org/ pump.io: http://pump.io/ GNUSocial: http://gnu.io/social/ Friendica: http://friendica.com/

Of course, you're bound to find a much geekier crowd here than twitter, G+, etc... but, that shouldn't matter too much to HN readers. ;)
