I recently added “repost-of” support to Micro.blog’s Micropub API implementation. This lets you pass an extra URL — the post you’re writing about — in clients like Micropublish. There’s deliberately still no concept of a retweet or repost, though.
When I wrote last year about Instagram and reposts, I was concerned with introducing features that could be abused or lead us back to reinventing Twitter’s problems. There’s even more evidence now that quick reposting shouldn’t be implemented blindly. Look what happened on Soundcloud:
Similar to Tumblr’s reblog or Twitter’s retweet, reposts were designed as a way to help new music spread virally. But from the start, artists abused the feature by constantly reposting their own tracks, pushing them back to the top of their followers’ feeds every few days.
For Micro.blog, I believe the right approach is to first introduce a simple “quote” feature. This UI would be streamlined to support quoting a sentence out of a blog post, with your own thoughts tacked on. It would fit with the spirit of easy posting in Micro.blog, but it would encourage more thoughtful posts and naturally scale up from traditional linkblogging.
