the 2 things are microformats to mark up your content for structure and webmention to tell another site about it
brid.gy accepts those webmentions, adn if you say in reply to a tweet, brid.gy sees that and posts it as a tweet
so there is one category where you have co-operating servers, and magic when you connect to a silo
brid.gy transaltes from theis common protocol to each of the silos own APIs - you need to know to send webmentions
the original brid.gy translates the facebook or twitter content into a microformatted block, that links back to FB
I'm imagining disasters and problems -I remember trackback drowning in spam
silos fight spam hard, so they are likely to be less spammy
spam filtering and fighting is part of any communication system you'll run something that helps this
right now there is no way to POSSE to instagram - so we use a trick to add a link to your site from IG
securing login is fundamentally hard - the great idea of IndieAuth is to use the big companies' hard work for that
do we have to bring back their river to our site?
now the silos have a good reading experience - they do the feedreader well
you can plug your friends sites into a feedreader and follow that way
Darius C. Dunlap:
one fo the things that friendfeed did well was let you make aghost version fo your friends from frrds to follow
keeping track of your own posts is valuable for yourself and letting you look at yourself.
the big thing that facebook has is they are the one place where everyone is. What do they do when they aren't?
one of the things I can do easily with twitter or facebook is fave, share, comment - we need to make indie as easy
if we build a good micropub client for android and ios and web, it doesn't matter so much about each site
