Backfeed is an important element in breaking out of silos like Twitter, Facebook, and others. Backfeed means if I post something from my site to e.g. Twitter, that the responses to it (likes, answers) also become visible on my site. So that when those silos inevitably go away and get replaced, my interactions are still available on my own site and available in my own database. Ryan Barrett of the valuable backfeed service Bridgy writes about the difficulties of creating backfeed (with lots of things to figure out for each additional silo), and wonders about making backfeed possible without additional or separate code. Sort of how IFTTT allows you to create your own recipes to let various applications you use talk to each other.
An example of backfeed in action:
the tweet, notice the repost and likes.
On Twitter people responded, with a repost and 2 likes.
Which Brid.gy sends back to my site, so I can show it underneath the original article:
the article showing the repost and likes as well
Through this, I can use Twitter to reach people and interact with them, without actually going to Twitter myself. I post on my site, it gets automatically sent to Twitter in the background, where people respond, which I see directly on my own site as incoming reactions. A full conversation on Twitter can be done completely on my own site this way. When Twitter dies, which it will, they will take all their data with them and all conversations will be lost. Yet, my Twitter interactions through my blog will remain available to me. Losing conversations isn’t necessarily a bad thing, but I’d rather decide myself which conversations to keep and which to remove, than let some third party or outside event be the judge of that.
Backfeed is an emerging key bit of internet plumbing, much like RSS already is for a long time. Making that plumbing easier will be of tremendous use.
