@stefan While share to mastodon didn't recognize my friendica instance as a valid Mastadon instance, it did recognize both my Soapbox and GNU Social accounts as valid, but neither works right, GNU Social just shows a pop-up window indicating "internal server error NO SUCH USER FOUND" whether I'm logged in or not, if I am logged in it shows my personal preference for the GNU Social interface and a log out button while if I'm logged out it shows the default interface and a log in button. On my Soapbox account it just opens a pop-up for a new post with no info pre-populated in the text input box.
