I just whipped up a little PWA to make my life on the #fediverse a bit easier: share2interact
. It's a web share target that forwards the shared link to your ActivityPub instance's Authorize/Lookup endpoint.
I built this because it's meaningless to follow hashtags from single-user ActivityPub instances(and impossible on old versions of mastodon and all versions of microblogpub), so I have an backup/lurking account at @dschep@mastodon.social to follow hashtags and browse on mobile via apps like megalodon.
This new little app allows me to more easily open toots & other ActivityPub objects (such as user profiles) from any Android app in another ActivityPub service in a browser.
