I'm lobbying friday (it's like gina) devs to include it for their post links, and I'm already using it for post links when sharing stuff in chats. I'm usually on either ecency or peakd and my links would be to one of those. Users on a platform other than what I link to ended up:
a) editing the link to go to their platform of choice
b) on a platform they don't use
c) accidentally interacting on the wrong alt (some ppl use various platforms to keep alts separate)
d) get the idea that I'm promoting a particular platform

With hivelink (hivel.ink), I can just replace the front part of a url and those problems all go away. Super simple tool that solves a few problems when presenting links to Hive posts
