How would share buttons work given lemmy is federated (vs a unique instance)?
For example in the screenshot (twitch clip), if you want to share on reddit you click the reddit button, but what button are devs supposed to put to share in the fediverse? Do they pick an instance of their choice?! Is this a weakness of a federated platform or what?
If it were me, when you click the "share to Lemmy" button, I'll just show a drop down list of most popular instances, followed with a "Custom..." item at the bottom where people can type their instance's domain name.
Not sure if you remember an extension called Tumblr Post, you'd log in and then you could share to Tumblr. I'm guessing that's the only real way short of registering a protocol.
You'd have to type in your instance name upon tapping the button
You could have a settings page that lets you set your instance name and then twitch (or whatever service you're using would store that along side your other user data)
It just assumes one of the most popular instances.
But without some central registry there's no way to know what is your home instance.
Edit: something like what Android does for Activities could work as well. But not sure how to handle that on a PC. ... In Android they could just start a generic Intent to view Lemmy and it could then launch whichever app you have installed to handle that intent.
It would be cool if there was a browser plugin that will automatically replace any (or reddit/facebook, etc) share-to button with a share to lemmy button.
