@Aethel Few ways...
To introduce things to others that you know more closely you can:
1 / Install it for them
(kinda like saying to grandma after installing rather than explaining), and then just remind them but usual messenger or email to try go to it when you are there or when live chatting switch to the better chat place/#app...
2/ Being on both and using both - slowing more #Skred than others (soft manipulation)
3/ Adding in your descriptions of other profiles you have skred or whatever app as a gradual thing they see.... and maybe link to the installer page. ☑️
Other ways welcome on this thread...
