The Potential of Crossposting
This does not have to be the only place you see this post. If I decided to, it could be seen on Tumblr or Mastodon, Medium or Twitter.
Many go out of their way to do this. Crossposting offers the distinct advantage of reach. If your followers vary on each platform, the scope of potential viewers increases dramatically. And that is usually the argument you hear for pushing content onto different channels. More eyes and ears.
What about an appeal to augmentation? Can one platform allow you to connect a post to other posts more easily? Does another allow you to annotate the post while others do not?
If all crossposting has going for it is reach, then we are losing potential for content to not only be seen in different places but to do different things.
